- New "Update sound" cue (CueId.Update / update.wav). Plays just before an
update starts installing, on every path (manual, background-silent,
startup-silent), so a silent background update gives an audible heads-up
before RemSound closes to restart. Per-profile mute + custom-sound override
in Preferences, same infrastructure as the other cues:
* Profile.EnableUpdateCue + RemSoundSettingsStore Load/Save + round-trip
* MainForm updateSound field, TryLoadCueSound, play in InstallUpdateAsync
gated by LoadEnableUpdateCue
* PreferencesDialog "Update sound" CueRow + ResolveCueFilePath mapping
* update.wav shipped in sounds\ via csproj Content
- Single-instance "switch to the running copy" now actually brings the window
to the front. The second copy grants the running copy foreground rights via
AllowSetForegroundWindow before signalling, and lingers briefly so it can
raise itself before we exit — without this, Windows' foreground lock left
the running window only flashing in the taskbar (Ed's report).
- Docs: About box v3.2 block, RELEASE_NOTES.md, manual cue section (now seven
cues, with the update cue described), MANUAL.md regenerated.
- Version bumped 3.1.3 -> 3.2.0.

Fixes the chained-fault runaway Andre hit after an update (multiple copies
stacking, audio climbing to deafening, terminal kill to recover).
- Single-instance lock (SingleInstanceCoordinator + SingleInstanceDialog,
wired in Program.Main). A named mutex makes two copies impossible. A second
launch offers: switch to the running copy (default; surfaces it from the
tray via a named activation event), or force the running copy closed and
start fresh (Process.Kill, retried elevated if the target is elevated).
This is the structural fix that makes the stacking runaway impossible.
- Prompt-free update exit. InstallUpdateAsync sets updatingInProgress before
Application.Exit(); the close path's skipPrompt now honours it, so no
unsaved-changes dialog (whose default button is Cancel) can abort the
update's restart.
- Read-only persistence fix. BuildCurrentProfile now carries
currentProfileReadOnly into the saved snapshot. Previously a deliberate
save of a locked profile wrote ReadOnly=false, silently unlocking it on
disk — which re-armed the save prompt that then blocked the update.
- In-process double-install guard. updateInstallStarted stops the ~4 s
startup check and the background poll both staging an install + helper.
- Docs: About box, RELEASE_NOTES.md, readme.html + MANUAL.md ("Only one copy
of RemSound runs at a time").
