File > Quick Connect... and a matching Profiles-tab button open
ProfileDialog in a new quick-connect mode (Name/Tags/Folder hidden,
Name validation skipped) and hand the resulting in-memory profile
straight to a session tab -- nothing is written to the profile
database. The tab title is derived from host/username/protocol for
display only. A Quick Connect tab's context menu gets a "Save as
Profile..." action, shown only on tabs that were never saved, that
opens the normal profile dialog pre-filled to persist it afterward.

Only the visible tab syncs the clipboard, but a tab in the background
missed local clipboard changes and kept a stale remote clipboard when
switched to, so with two RDP/VNC sessions only the one last copied in
worked. A tab now pushes the current local clipboard to its remote on
show.

Local copies were de-duplicated against the last synced text with no
expiry, so one lost send made re-copying the same text a no-op; every
open tab listened to the system clipboard, letting background sessions
overwrite it and forwarding one tab's update to all others; and RDP
never sent the initial Format List MS-RDPECLIP requires after Monitor
Ready, which the server can re-send mid-session (e.g. rdpclip.exe
restart), leaving sync dead until reconnect. Announce failures are now
logged to the event log instead of silently dropped.

The inline prompt bar previously had no explicit styling and rendered
in the same color as the rest of the tab; a tab showing the prompt in
the background had no indication anything needed attention. The bar
now uses a solid QPalette::Highlight fill with HighlightedText for the
label and a hand-drawn contrasting badge, and a background tab gets a
"(Needs input)" title suffix plus a distinct tab-bar color.
A first pass at the tab color (#6a1b9a) was reported unreadable in
dark mode; replaced with #ab47bc, tuned to match the visibility of the
existing connection-state colors.

Closes#21. SSH and RDP profiles previously hard-required a username
to even save the profile; that validation is dropped, and
SessionTab::requestConnectOptions() now prompts for it at connect
time when blank, reusing the existing password-prompt bar in
unmasked mode -- the same pattern already used for a blank password.
VNC's username is trickier: most VNC servers never use one (plain VNC
Authentication and no-auth don't), only the two Apple auth schemes
(security types 30/33) do, and which auth method gets used isn't known
until mid-connection, after the server's security-type list has been
negotiated -- too late for the pre-connect prompt SSH/RDP uses. Adds a
new async request/response pair to SessionBackend, usernameRequested()
signal / provideUsername() slot, mirroring the existing SSH host-key-
confirmation pattern. VncSessionBackend pauses its state machine right
before computing an Apple-auth response if no username is available --
without consuming the already-buffered prime/host-key bytes, so
resuming re-parses them identically -- emits the request, and resumes
via provideUsername(). Cancelling (or submitting blank) fails the
connection cleanly instead of sending Apple auth an empty username.
The username is kept on the tab's in-memory profile copy for its
lifetime, not written back to the saved profile, matching how
passwords are already handled.

VNC has no equivalent of RDP's MS-RDPEDISP to request a different
resolution from the guest, so a high-resolution remote desktop
previously always got shrunk to fit the window, making text
illegible. Adds a per-tab "Display Mode" choice (tab-bar right-click)
between the existing scale-to-fit behavior and a new actual-size mode
that renders the framebuffer at its native pixel size inside a
QScrollArea. Reuses VncDisplayWidget's existing scale-to-fit render
math unchanged -- it degenerates to an exact 1:1 mapping once the
widget is fixed to the remote's own size. Persisted like the terminal
theme preference.

Implements RFB (RFC 6143) directly against QTcpSocket. No permissively
licensed VNC client library exists to vendor the way FreeRDP was for RDP:
LibVNCClient is GPLv2, gtk-vnc is LGPL but GTK-tied, and vendoring either
would force a licensing decision on the whole (MIT) project. This is
from-scratch protocol code instead, threaded like SshSessionBackend (a
QObject on its own QThread driven by Qt's own async socket signals)
rather than RdpSessionBackend's manual worker-thread/blocking-loop
pattern, since QTcpSocket is already async.
Scope, matching SessionTab's existing SSH/RDP dispatch pattern
(session_backend_factory.cpp, session_tab.cpp's widget construction and
signal wiring) and VncDisplayWidget mirroring RdpDisplayWidget's
scale-to-fit rendering:
- Protocol handshake: RFB 3.3/3.7/3.8 negotiated explicitly (the
SecurityResult message only exists in 3.8; pre-3.8 servers signal auth
failure by closing the socket, which the disconnect handler accounts
for)
- VNC Authentication (DES challenge-response, via OpenSSL's classic DES
API) and no-auth security types
- Raw + CopyRect framebuffer decoding into a persistent QImage, requesting
a fixed 32bpp format whose byte layout matches QImage::Format_RGB32
directly (same zero-conversion trick RdpSessionBackend uses for
FreeRDP's GDI buffer)
- Keyboard (Qt key -> X11 keysym, including the Unicode-beyond-Latin-1
keysym convention) and mouse/wheel input forwarding
Explicit non-goals for this pass (see docs/PROGRESS.md for the full
list): Apple's Screen Sharing auth (so this can't yet reach macOS's
built-in VNC server), compression encodings beyond Raw/CopyRect, dynamic
resize, remote cursor shape sync, clipboard sync.
19 unit tests (tests/test_vnc_session_backend.cpp): pure-function
coverage (DES key prep verified against an independently documented test
vector for password "COW", X11 keysym mapping, socket-error mapping) plus
state-machine coverage against a scripted in-process fake RFB server
covering all three protocol-version handshake shapes, auth success/
failure, unsupported security types, and pixel-accurate Raw decoding.
That harness caught a real re-entrancy bug: QAbstractSocket::abort()
synchronously re-emits disconnected() before returning, so
failConnection() calling it was silently letting a second, generic
disconnected-socket handler overwrite an already-correct, specific error
message.
Also verified live against a real, independently implemented VNC server
(TightVNC on Windows): connect with VNC Authentication, correct
framebuffer dimensions and pixel data, clean disconnect, reconnect.

The RDP session pipeline never accounted for display scale: it
requested a desktop canvas sized in Qt logical pixels (never
multiplied by devicePixelRatio()), and FreeRDP_DesktopScaleFactor/
DeviceScaleFactor were read but never actually set anywhere. On a
HiDPI monitor this meant the remote session rendered assuming a
96 DPI / 100% display, and the resulting canvas got stretched
locally — ClearType's subpixel hinting doesn't survive that kind of
resampling, producing distorted glyph shapes and color fringing
rather than plain blur.
RdpDisplayWidget now reports physical pixel dimensions and the real
devicePixelRatio (recomputed on resize and on screen changes, e.g.
dragging the window to a different-DPI monitor). RdpSessionBackend
maps that to the nearest FreeRDP-legal scale value ({100, 140, 180},
per MS-RDPEDISP and FreeRDP's own reference client) and sets it at
both connect time and on every dynamic resize, including the
FreeRDP_MonitorOverrideFlags required for the values to actually be
honored rather than silently ignored.
While testing this against real infrastructure, found and fixed two
related (pre-existing, not caused by this change) resize issues:
- A stale-frame race where the old frame could be drawn at the wrong
scale for a moment after a resize, before a correctly-sized one
arrives — now the frame is cleared during that transition instead.
- No debounce on outgoing resize requests — every single resize event
fired an immediate request to the server, which can visibly
contribute to host-side redraw glitches during rapid layout churn
(e.g. right after connecting). Coalesced into one request per burst,
plus an explicit refresh-rect request after each resize completes
as a best-effort nudge for hosts that don't fully repaint on their
own.
A separate, deeper issue was also found during testing (the remote
guest's actual resolution sometimes not changing despite the resize
channel reporting success) and is tracked separately, not fixed here.

Fix RDP keyboard input using FreeRDP's authoritative X11-keycode-to-scancode
table instead of ad hoc bit math, which misread punctuation keys as unrelated
letter keys (e.g. apostrophe as B) because X11 keycode numbering only
coincidentally overlaps PC/AT scancodes.
Add bidirectional clipboard sync (CF_UNICODETEXT) over the cliprdr channel,
and RDP pointer/cursor shape sync so the local cursor reflects what the
remote OS wants displayed (resize handles, text I-beam, etc.) instead of
staying a static arrow.

Replace the modal RDP/SSH password dialog with an inline prompt bar
embedded in the session tab instead of a separate popup window. Add
per-tab terminal font size controls (increase/decrease/reset/set
exact point size) via the tab context menu, with the chosen size
persisted across sessions.
