packaging: pin vendored FreeRDP's own version, stop git-tag bleed-through

third_party/FreeRDP is vendored in-tree rather than as a separate git
submodule, so its build-time git_get_exact_tag() call (in
cmake/GetProjectVersion.cmake) was resolving against OrbitHub's own git
tags instead of any real FreeRDP release tag. Its version-extraction regex
then greedily matched the last three dot-separated numbers of our tag
(e.g. v2026.9.14.2 -> "9.14.2"), mislabeling FreeRDP's own libraries in
packaged builds (libfreerdp9.so.9.14.2 instead of the real
libfreerdp3.so.3.23.1) -- self-consistent within a build, but misleading
and drifting release to release.

Adding .source_tag makes GetProjectVersion.cmake take its file-based
branch (which it already prefers over the git-tag branch) instead.

+the `.dmg`, also install `SetFile` (via Xcode's "Additional Tools", from
+[developer.apple.com/download/all](https://developer.apple.com/download/all))
+or `brew install fileicon` — packaging still works without either, just with
+the generic disk image icon.
+
+```bash
+./packaging/macos/build-dmg.sh
+```
+
+This runs `cmake --install`, then `macdeployqt` to bundle Qt frameworks and
+plugins into the `.app`, then re-signs the bundle (ad hoc, since there is no
+Developer ID certificate) so it passes macOS's launch-time code-integrity
+check. The result is unsigned/unnotarized, so first launch requires

+# Flathub Submission Readiness
+
+Tracks OrbitHub's readiness for submission to Flathub. This is a separate
+checklist from `docs/PROGRESS.md`'s development milestones, since Flathub
+submission is an external process with its own requirements.
+
+## Status
+
+| Item | Status |
+|---|---|
+| Production manifest with pinned, reproducible git source | Done — `packaging/flatpak/flathub/org.darksingularity.OrbitHub.yml`; commit pin updated at each tagged release |
+| `flathub.json` for build settings (`only-arches`, etc.) | Done — `packaging/flatpak/flathub/flathub.json` |
+| Offline build (no network fetches during build) | Verified — no `FetchContent`/`ExternalProject`/`curl`/`wget` in CMake; all vendored deps committed in `third_party/`; confirmed with a real `flatpak-builder` build |
+| SSH client available inside the sandbox | Verified — provided by the `org.kde.Platform` runtime base, no packaging needed |
+| `--filesystem=home` removed | Done — narrowed to `--filesystem=~/.ssh` (read-write, needed for `known_hosts` and SSH config) |
+| SSH known-hosts trust persists with narrowed permissions | Verified in sandbox against real infrastructure |
+| RDP works with zero filesystem permission | Verified — FreeRDP's cert trust store lives outside the sandboxed home path concerns entirely (see below) |
+| Private-key/export file pickers use the desktop portal | **Verified interactively** — `QFileDialog`'s Browse button correctly opens the native GTK portal chooser ("Select Private Key"), which can browse the full filesystem via user consent regardless of the sandbox's static `~/.ssh`-only grant |
+| Current, supported KDE runtime | Verified — upgraded to `6.11` (linter's recommended latest); confirmed the app still builds and launches against it |
+| Desktop entry validates | Verified |
+| Application icon validates | Verified — PNGs at all standard hicolor sizes, matching the real app icon |
+| MetaInfo/AppStream validates | Verified via both `appstreamcli validate` and Flathub's own `flatpak-builder-lint appstream` (0 errors either way) |
+| Screenshots present | Done — profiles view, active SSH session, active RDP session, all captured against real (test) infrastructure |
+| Release information present | Done — `<releases>` block with `v2026.9.8` (add an entry per future tagged release) |
+| Developer/project URLs present | Done — homepage, bugtracker, vcs-browser, developer block |
+| Architecture support decided | `x86_64` only (no ARM hardware available to test FreeRDP/WinPR on aarch64), set via `flathub.json`'s `only-arches` |
+| Flathub manifest linter passes | One expected finding remains: `finish-args-ssh-filesystem-access` (see below) — everything else passes, including `only-arches` placement and runtime-version currency |
+| AppStream linter passes | Passing (both `appstreamcli validate` and `flatpak-builder-lint appstream`) |
+| Clean install works without host dependencies | Verified via local `.flatpak` bundle install and launch, on both KDE 6.10 and 6.11 runtimes |
+| Bundled-dependency license files installed per Flathub's `$FLATPAK_ID` convention | Partially done — path fixed from `share/licenses/orbithub` to the required `share/licenses/org.darksingularity.OrbitHub`; FreeRDP's and KodoTerm's `LICENSE` files now installed there too. **`libvterm`'s vendored copy has no `LICENSE`/`COPYING` file at all** — needs to be pulled from upstream and added as `third_party/libvterm/LICENSE` before submission (README claims MIT; not verified against an actual license file in-tree) |
+
+## ⚠️ Not yet addressed: Generative AI disclosure policy is a real acceptance risk, not a checklist item
+
+See the dedicated section below — unlike everything else on this page, this
+isn't something more packaging work resolves.
+
+### `finish-args-ssh-filesystem-access` — expected, needs a submission-time justification
+
+Flathub's linter flags *any* `~/.ssh` filesystem grant by policy — it's not a
+bug in this manifest, it's a deliberate prompt for the submitter to justify
+the access during PR review. Checked the linter's own exceptions list:
+several existing SSH-client apps already have this exact permission approved
+with justifications like *"Read-only access to ~/.ssh is required to load
+SSH keys for connecting to devices over SSH"* and *"Needed to manage SSH keys
+and configurations for connections"* — OrbitHub's case is the same pattern
+(read-write, specifically for `known_hosts` persistence and default identity
+file discovery). Include a similar justification in the submission PR.
+
+## ⚠️ Not yet addressed: Generative AI disclosure policy
+
+Flathub's [Generative AI policy](https://docs.flathub.org/docs/for-app-authors/requirements#generative-ai-policy)
+requires submitters to disclose "any AI-generated code, documentation,
+packaging, or other material" included in the app or its Flathub packaging,
+identifying "the affected parts and approximate extent." This is not a
+formality — it's evaluated at reviewer discretion, and reviewers may reject
+"based on the extent or role of generated material."
+
+OrbitHub's development has used Claude Code extensively — the app's C++
+source, this Flatpak packaging (manifest, metainfo, build scripts), and this
+tracking doc itself. Every commit in this repository carries a
+`Co-Authored-By: Claude Sonnet 5` trailer, which is itself effectively an
+existing disclosure trail. An honest submission disclosure needs to reflect
+that extent truthfully — not a token "some AI assistance was used" note.
+
+The same policy also prohibits AI tools from opening or automating the
+submission PR itself, or generating its commit messages, description, or
+review replies. **This means the actual submission PR — including its AI
+disclosure — has to be written and opened by a human, not drafted by
+Claude.** Not done, and not something this repo's tooling should attempt.
+
+This is a real acceptance risk that no amount of technical packaging work
+resolves — it's a policy/reviewer-discretion matter, separate from every
+other item on this page.
+
+## Related finding (not a packaging blocker)
+
+During permission-narrowing research, RDP certificate verification was found
+to be completely disabled (`IgnoreCertificate=TRUE`, all server certificates
+silently accepted including *changed* ones). This has been fixed separately
+in `src/rdp_session_backend.cpp` — FreeRDP's own trust-on-first-use
+certificate store is now used, matching SSH's known-hosts model. Not a
+Flathub-specific issue, but worth noting since it was found in the course of
+this work.
+
+## Explicitly out of scope for this repo
+
+- Opening the actual submission PR against `github.com/flathub/flathub` —
+  requires the maintainer's GitHub identity, done outside this repo, and per
+  the Generative AI policy above must be written by a human, not drafted here.
+- ARM64 build/testing — no hardware available.
+- Flathub's post-acceptance developer-verification step — done via
+  Flathub's own website after acceptance, using DNS control of
+  `darksingularity.org`.

+## Introduction
+
+OrbitHub is a native desktop application for organizing connection profiles
+and launching SSH and RDP sessions from one place, in a single tabbed
+window. It runs on Windows, Linux, and macOS.
+
+This guide covers everyday use: creating and organizing profiles,
+connecting over SSH and RDP, managing active sessions, and what to do when
+something goes wrong. It does not cover installation or building from
+source — see the project's `README.md` and `docs/BUILDING.md` for that.
+
+VNC support is planned but not yet implemented; profiles can be tagged for
+it, but connecting will show an "unsupported protocol" message for now.
+
+## Getting Started
+
+When OrbitHub opens, you land on the **Profiles** tab — a searchable,
+sortable list of every connection you've saved. Two toolbar controls in
+the top-right change how that list is presented:
+
+- **View**: `List` shows every profile in one flat table; `Folders` groups
+  them into the folder tree you've organized them into.
+- **Sort**: orders the list by Name, Protocol, or Host.
+
+Along the top of the window, a **Search** box filters by name, host,
+folder path, or tag as you type, and **Protocol**/**Tag** dropdowns narrow
+the list further. These filters, plus your last view mode and sort order,
+are remembered the next time you open OrbitHub.
+
+Along the bottom of the Profiles tab: **New**, **Edit**, and **Delete**
+buttons for managing the selected profile. The same actions are available
+by right-clicking a profile or folder, and from the **File** menu (`New
+Profile`, `New Folder`).
+
+To connect, double-click a profile, or select it and press the connect
+control — this opens a new tab for that session and connects
+automatically.
+
+## Managing Profiles
+
+A profile stores everything needed to reach one remote host. Open **New**
+(or **Edit** on an existing profile) to fill in:
+
+- **Name** — a label for the profile; shown on its tab and in the list.
+- **Host** — hostname or IP address.
+- **Port** — defaults to `22` for SSH, `3389` for RDP.
+- **Username** — the account to log in as.
+- **Domain** — Windows domain for RDP logins (leave blank for local/
+  workgroup accounts or SSH profiles).
+- **Tags** — free-form, comma-separated labels for filtering and grouping
+  (e.g. `prod, linux, db`).
+- **Folder** — where the profile lives in the Folders view.
+- **Protocol** — `SSH`, `RDP`, or `VNC` (VNC is accepted but not yet
+  connectable — see Introduction).
+
+Fields below Protocol change based on what you pick:
+
+**SSH**: **Auth Mode** (`Password` or `Private Key`), and if Private Key,
+a **Private Key** file path with a **Browse** button, plus **Known Hosts**
+policy — see [Connecting via SSH](#connecting-via-ssh) for what each
+policy means.
+
+**RDP**: **RDP Security** and **RDP Performance** — see
+[Connecting via RDP](#connecting-via-rdp).
+
+Passwords are never saved in the profile — OrbitHub asks for them each
+time you connect (unless you've set up private-key SSH auth, which needs
+no password to be entered per-connection if the key itself has none).
+
+## Organizing Profiles
+
+As your profile list grows, two independent tools keep it manageable:
+
+**Folders.** Switch the Profiles tab to `Folders` view to see profiles
+grouped into a tree. Create a folder from the **File** menu or by
+right-clicking in the tree (`New Folder`), and drag any profile onto a
+folder to move it there. Folders can nest inside other folders.
+
+**Tags.** Tags are independent of folders — a profile can be in one folder
+but carry several tags (e.g. `prod`, `linux`, `db` all at once). Use the
+**Tag** filter dropdown in the toolbar to instantly narrow the list to
+everything sharing a tag, regardless of which folder it's filed under.
+
+Combine both with the **Search** box (matches name, host, folder path, or
+tags) and the **Sort** control (Name / Protocol / Host) to find what you
+need quickly even with a large profile list.
+
+## Connecting via SSH
+
+Double-clicking an SSH profile opens a new tab with an embedded, fully
+interactive terminal — type directly into it as you would any terminal
+emulator. A **theme** selector lets you switch between `Dark`, `Light`,
+and `Solarized Dark`; your choice is remembered for future sessions.
+
+**Authentication.** Set in the profile itself:
+- **Password** — OrbitHub prompts for a password each time you connect.
+  It is never stored.
+- **Private Key** — point at a key file (via the profile's Browse button);
+  no password prompt unless the key itself is passphrase-protected.
+
+**Known Hosts policy.** This controls how OrbitHub reacts to a server's
+SSH host key — the mechanism that protects against a different machine
+silently impersonating a host you've connected to before:
+
+| Policy | Behavior |
+|---|---|
+| `Ask` | Prompts you to confirm trust the first time a host is seen, and on any later change. Recommended default. |
+| `Accept-new` | Silently trusts a host the first time it's seen, but still stops and warns if a previously-trusted host's key later changes. |
+| `Strict` | Never trusts an unknown host automatically — the connection fails until you've manually confirmed the host key some other way. |
+| `Ignore` | Skips host-key checking entirely. Only use this for throwaway/test environments — it removes protection against on-path attacks. |
+
+Trusted host keys are recorded in your system's normal SSH `known_hosts`
+file (the same one the `ssh` command line tool uses), so trust decisions
+made through OrbitHub or a terminal `ssh` session carry over to each
+other.
+
+## Connecting via RDP
+
+RDP sessions render in an embedded display surface inside the tab — no
+external RDP client window opens. Keyboard and mouse input go straight to
+the remote desktop while the tab has focus, and resizing the OrbitHub
+window renegotiates the remote resolution to match. Clipboard content
+syncs between your machine and the remote session automatically.
+
+**Authentication** uses the profile's Username/Domain fields; OrbitHub
+prompts for the password at connect time.
+
+**RDP Security** controls which transport-security layer is used to
+negotiate the connection:
+
+| Mode | Behavior |
+|---|---|
+| `Negotiate` | Lets the client and server agree on the strongest mutually-supported option automatically. Recommended default. |
+| `NLA` | Requires Network Level Authentication (credentials verified before a full session starts) — the modern standard for current Windows versions. |
+| `TLS` | Requires TLS-only security, without NLA. |
+| `RDP` | The legacy RDP-native security layer, for older servers that don't support TLS/NLA. |
+
+**RDP Performance** trades visual fidelity for responsiveness:
+`Balanced` (default), `Best Quality`, `Best Performance`, or
+`Auto Detect` (adapts based on the detected connection).
+
+**Server certificate verification.** The first time you connect to an RDP
+host, OrbitHub trusts and remembers its TLS certificate — the same
+trust-on-first-use model SSH uses for host keys. If that certificate ever
+changes on a later connection, OrbitHub refuses the connection rather than
+connecting anyway, since a changed certificate can mean either a
+legitimate server certificate renewal or an active
+machine-in-the-middle presenting a different one. The event log (see
+below) shows the specific fingerprints involved. If the change is
+expected — you rotated the server's certificate yourself — reconnecting
+after clearing the old entry from FreeRDP's certificate store will trust
+the new one.
+
+## Managing Sessions
+
+Every open connection lives in its own tab in the same window, alongside
+the Profiles tab. A tab's title and a colored state indicator show
+whether it's connecting, connected, disconnected, or failed. Closing a
+tab disconnects that session; opening a profile again starts a fresh one.
+
+Each session tab includes a collapsible **event log** beneath the
+connection surface — a timestamped record of connection state changes,
+warnings, and errors for that session. Controls above the log let you:
+
+- **Show/Hide Events** — collapse the panel when you don't need it.
+- **Filter** — a text box to search event text, and an `All` /
+  `Warnings` / `Errors` severity dropdown to narrow what's shown.
+- **Export Events** — save the current session's full event log to a
+  file, useful when reporting a connection problem.
+- **Clear Events** — empty the log for that tab.
+
+## Settings & Preferences
+
+OrbitHub remembers your preferences across restarts without any separate
+settings screen — they're saved automatically as you use the app:
+
+- Profile list: search text, view mode (List/Folders), Protocol/Tag
+  filters, and sort order.
+- Session tabs: terminal theme choice, and whether the events panel is
+  shown or hidden for new tabs.
+
+Profile data itself (names, hosts, tags, folder structure, and so on) is
+stored in a local SQLite database — see the README for its exact path on
+your platform. Passwords are never part of that stored data.
+
+## Troubleshooting
+
+**"Host could not be resolved"** — the hostname in the profile can't be
+looked up by DNS. Check for typos, or try the host's IP address directly
+to confirm whether it's a DNS problem or something else.
+
+**SSH connection fails immediately, no prompt** — double-check the
+profile's Port (default `22`) and that a firewall or network path isn't
+blocking that port from your machine.
+
+**RDP: "Authentication failed. Check username and password."** — confirm
+Username and Domain are correct for the target server; some servers
+require the domain to be set explicitly even for local accounts.
+
+**RDP: "RDP security negotiation failed. Try a different RDP security
+mode."** — the server doesn't support the security mode selected in the
+profile. Try `Negotiate` first, or a more specific mode if you know what
+the server requires.
+
+**RDP: connection refused with a certificate-changed message** — see
+[Connecting via RDP](#connecting-via-rdp) above; this is expected,
+protective behavior, not a bug, whenever a previously-trusted server's
+certificate is replaced.
+
+**SSH: connection hangs at "Ask" waiting for host-key trust** — check
+that policy's behavior under
+[Connecting via SSH](#connecting-via-ssh); switching to `Accept-new` avoids
+the prompt for genuinely new hosts while still protecting against a later
+key change.
+
+If none of this covers what you're seeing, a session's exported event log
+(see Managing Sessions) is the most useful thing to include when asking
+for help or filing an issue.
