listen() was the whole of the single-instance check and it cannot be one:
a Windows named pipe takes a second server on the same name rather than
refusing it, and everywhere else removeServer() first takes the live socket
away from the instance holding it. Starting Dikte over a running Dikte then
left two whole copies up, two tray icons and all, and the newer one's
sweep() killed the whisper the older one was answering dictations with. On
a machine that sleeps instead of logging out, that is one Start Menu click
away, and it cost a real dictation before it was understood.
A QLockFile in the data directory closes the race on all three systems,
taken before the QApplication is even built, and behind it the probe is the
side-effect-free status verb: the Settings window opens as the sign of life
only when a bare second start deliberately asks for it, not as a byproduct
of a probe racing a forwarded toggle. The two Windows relaunch dances
collapse into one ipc.respawn.
The checkout installer and the packaged setup each kept an autostart the
other could not see, so a machine that tried both started two copies at
every sign-in: each autostart now removes the other's entry, the silent
every-start repair backs off from a Run value whose target still exists,
and each uninstaller deletes the shared dikte.cmd only when the shim
names its own install.

The dshow parser pinned the bracketed prefix to the `[dshow @ ...]` the
older builds print, and ffmpeg 8 writes `[in#0 @ ...]` there instead: on a
current install every line fell through the anchors, the device list came
back empty, and a dictation with no microphone picked could not start at
all. The prefix is now any bracketed tag, which the anchors and the quoted
name still keep apart from the error lines. Pinned with a listing taken
verbatim from ffmpeg 8.1.2 on Windows 11, third kind marker `(none)`
included.

A backslash only separates on Windows, and this test also runs on the
Linux that checks the Windows half.

Windows joins the three systems as its own entry in each table: DirectShow
through ffmpeg for capture, the Win32 clipboard and SendInput for the paste,
RegisterHotKey for the global shortcut, and the whisper.cpp and llama.cpp
Windows zips (the OpenBLAS whisper build, which transcribes about twice as
fast on a plain CPU). Settings go to APPDATA, data to LOCALAPPDATA, and
install.ps1 adds the Start Menu entry, the dikte command and an optional
autostart. Meetings are not supported yet: Windows offers nothing to record
the far side from.
Porting surfaced three fixes that were not Windows specific:
- A stopped or overlong download tried to delete its .part file while still
holding it open, which Windows refuses. The unlinks now wait for the handle.
- The CLI transcribed files without handing the local servers their settings
first, so a local provider failed with "no model downloaded" wherever the
GUI had not run in the same process.
- The audio content types are pinned instead of asked of the registry, which
answers differently machine to machine.
One fix is Windows specific but sits in shared code: shutdown() does not end
a blocked recv there, so stopping a request also closes the socket handle.
