Replace the generated cmd.exe + robocopy update helper — which silently
failed on some machines — with an in-app C# installer:
* Stage the new version to a per-user temp folder off the install and run
the new RemSound.exe from there, so nothing in the install is locked by
the updater itself.
* Wait for the old process to fully exit (real WaitForExit), then
back-up-and-swap files in C# with retry + rename-aside; roll the install
back to the previous version on any failure, so a failed update can never
leave a half-installed RemSound.
* Log every step to updater.log; clean up old stages and legacy batch
artefacts on launch. Removed the old BuildInstallScript batch generator.
Route the "RemSound is already running" dialog and its follow-up message
through ForegroundDialog so they surface in front from a background-relaunched
copy, matching the earlier post-update fix.
Docs: rewrite the readme update sections for the new mechanism, regenerate
MANUAL.md, refresh the About-box changelog and RELEASE_NOTES.

- Recover an unplugged/replugged output sound card automatically (issue #5):
detect the dead WASAPI device and remember the receive-output selection so it
re-ticks and re-opens when the card returns.
- Adaptive per-card WASAPI buffer target sized to each card's pull chunk, held
stable so it never flits about under CPU/network load.
- Consolidate all per-user data (config, profiles, logs, sounds) into one
"user settings and logs" folder; migrate every older layout; exclude it from
the updater so custom cue sounds now survive updates.
- Mic-privacy detector: warn once when a Windows-blocked mic is switched on, or a
profile loads with one already on.
- All warning/notice dialogs now come to the foreground even when minimised.
- Apply volume + mute on profile load (were saved but not restored).
- Crash-safe (atomic) profile/config saves.
- Fix two resource leaks (push-mode capture MMDevice; UPnP DeviceFound handler).
- Remove dead code (baseline-diff machinery, dead ASIO probes, no-op stubs).
- Docs: readme.html, MANUAL.md, About-box changelog and release notes for v3.5.

Builds on the v3.4 freeze (dd70613) with the fixes and tuning from live testing,
plus the v3.4 documentation pass.
Audio (receiver):
- Per-device WASAPI drift correction in MultiOutputPlayout. A pull-side resampler
(mirroring SessionPlayout's proven corrector) holds each output device's buffer at
a fixed low depth, cancelling the slow clock drift that made WASAPI peers "lag
apart" over long sessions. Feed-forward clock-ratio measurement plus a gentle
depth-restoring term; the first measurement window is discarded because WASAPI
start-up priming poisons it. ASIO already self-corrected; this brings WASAPI level.
- Output device buffer requested at 5 ms (WASAPI clamps it up to the device's minimum
period, ~10 ms) instead of 15 ms, since the corrector keeps it fed — a free saving.
UI / accessibility (MainForm, Program):
- Startup notices (what's-new About box, Realtek warning) now run one at a time via a
single sequence instead of separate BeginInvokes, so they no longer stack into
nested modals that couldn't be closed. The loading splash is skipped for a
tray-bound quick switch.
- Quick profile switch keeps RemSound in the tray if it was there, and plays the
switch cue immediately on click.
- Profile-switch cue now plays on click for every switch path (recent menu, quick
switch, File > Open) and no longer on a fresh start into the first profile. It was
also previously dead on the rebuilt form (pendingProfile was nulled first).
- Realtek ASIO toggle's accessible name now reads "Enable"/"Disable" to match the
visible text, instead of "Toggle" (screen reader read the wrong word).
Docs (plain English):
- RELEASE_NOTES.md: v3.4 entry.
- About dialog: v3.4 "what's new".
- readme.html (the canonical bundled manual): quick switch, the hotkey read-outs, the
new profile-menu-open cue, Realtek auto-detect/disable, and the config-folder path.
- MANUAL.md regenerated from readme.html via sync-manual.py so the two stay in sync.

Freezes the v3.4 feature set (everything since the v3.3 public release):
- Fix the receiver handle leak: the 3-second device-refresh timer reopened the
configured ASIO driver every tick, and Realtek's ASIO driver leaks Event+Mutant
handles on every open. Cache the ASIO probe per driver so it is opened once.
- Realtek ASIO block: detect a Realtek ASIO driver, offer once to disable it, and
never touch it again if disabled; Options-menu toggle to reverse. Global config.
- Device hot-plug is event-driven (AudioDeviceChangeNotifier) instead of a 3s poll;
debounced refresh, falls back to polling if registration fails.
- Quick profile switch: new global hotkey opens an NVDA-friendly popup of all
profiles (current marked); Enter/click switches; plays a new "profile menu open"
cue with Preferences mute + custom-sound.
- Announce assigned global hotkeys on the controls/menu items they drive (NVDA reads
"press X anywhere"). File > Open already had Ctrl+O.
- Held-back changes folded in: config-folder migration, codec-column fix, Tailscale
endpoint network-prune, empty-password guard, and the handle-leak diagnostics
(ProcessSelfMeter, HandleTypeProbe).
Version bumped to 3.4.0.

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").

* New "Opus, live latency" codec mode: 2.5 ms frames (120 samples/ch at 48 kHz)
via the float-input encode path. End-to-end codec delay drops to ~5 ms (vs
~12.5 ms at standard 10 ms Opus). Test on LAN: 400 pps/lane, zero missed /
reordered / duplicate packets, ~15 ms one-way saved end-to-end.
* Wire-format change: AudioFormatInfo.FrameDurationMilliseconds renamed to
FrameSamplesPerChannel (int sample-count at announced sample rate). Removes
the lossy 48000*ms/1000 conversion that couldn't represent 2.5 ms. v3 <-> v3
exact; v3 <-> v2 still passes audio (Opus decoder is self-describing from
packet TOC) but v2 side over-sizes its buffer wildly. v2.x profiles auto-
migrate via <120 sentinel rule in RemSoundSettingsStore (anything below 120
is treated as legacy ms and multiplied by 48). Profile JSON key kept as
OpusFrameMilliseconds via [JsonPropertyName] so old profile files still load.
* Codec dropdown rebuilt with use-case names: "PCM 48K 24 bit - uncompressed",
"Opus, broadcast quality - loss tolerant", "Opus, live latency - for jamming
and monitoring". Middle 10 ms option retired; saved 480-sample profiles
collapse to broadcast quality (safer-side default).
* Profile auto-resume after self-update: RemSoundUpdater writes a one-shot
_resume-after-update.txt sentinel containing the active profile title before
exit; Program.Main reads + deletes it on next start and silently loads that
profile, skipping the picker. Helper batch's robocopy /XF excludes the
sentinel and the failure-branch cleans it up if the install aborts. Falls
through to normal startup behaviour (StartWithProfileTitle or picker) if the
sentinel is missing, empty, or names a profile that no longer exists.
* Read-only profile saves now go through on explicit Ctrl+S / File -> Save
with a one-time TaskDialog warning ("Save anyway" / "Cancel" + Do-not-show-
again). Lock continues to suppress the automatic unsaved-changes prompt on
close / profile switch (its main job). AppConfig.SaveOnReadOnlyMessageSuppressed
renamed to SaveOnReadOnlyWarningSuppressed; v2.x suppression flag is silently
discarded since the behaviour changed and the user needs to see the warning
once on each machine.
* Manual (readme.html) updated: codec table rewritten with the three new
choices and corrected bandwidth figures, send-rate description updated, new
sections "The same profile picks up automatically after an update" and
"Saving on purpose while a profile is locked".
* Subsumes the never-separately-released v2.2 work: native Opus encoder
(~97% less per-second memory churn on Opus send path via Concentus.Native),
efficiency tidy-ups (item 4 ASIO probe rate, item 6 WaitHandle, item 7
snapshot cache, items 14/16 heartbeat + discovery), legacy cleanup
(items 30/34/35/36: KeepAlive infrastructure, drift drop/repeat/accumulator
fields, fan-out cache stat). New diagnostic columns cpu/memMB/wsMB/
allocKBps/captureMs/sendMs/recvMs/renderMs gated on Enable-logs.
About dialog updated with v3.0 block at top; v2.2 block retained for the
subsumed work.

Opening an ASIO driver takes 1-3 seconds, synchronously, during MainForm
construction — confirmed in logs as a ~2.8s dead gap on an ASIO-profile
launch (a WASAPI-only launch is ~131ms for the same stretch). During that
gap the main window is blank / "Not Responding" and looks hung.
New AsioLoadingSplash shows a small "Loading audio driver, please wait..."
window on its OWN dedicated STA thread with its own message loop, so it
stays painted while the main thread is blocked opening the driver.
Program.cs starts it before new MainForm() and dismisses it after.
Deliberately, the ASIO driver open stays on the main UI thread — that
STA/message-pump thread is what ASIO/COM drivers are most compatible with,
and moving the open off it risks breaking drivers that can't be tested.
Only the cosmetic splash moved to a side thread; no ASIO/driver code is
touched. Splash shows only for profiles with an ASIO driver selected;
WASAPI-only profiles build fast and get no splash.
Version bumped to 2.0.0 to mark the milestone.
No wire-format or audio-pipeline changes — v1.5 through v2.0 interoperate.
