BluetoothAudioManager
- Replace Timer.scheduledTimer polling with DispatchSourceTimer on a
utility queue so main-thread back-pressure no longer stalls the 3s
connect-detection cadence.
- Distinguish "host controller unavailable" from "powered off" via a
new bluetoothIsPoweredOn() helper, so transient IOBluetooth registry
blips at launch no longer clear connectedDevices.
- Re-read device metadata (name, type, battery) at +500ms and +2s after
IOBluetoothDeviceConnectedNotification to catch IORegistry's
late-population window; the existing HUD wait-task then updates the
shown battery in place.
- Declare BluetoothAudioDeviceType: Equatable to support the
change-detection diff in the re-read pass.
LockSoundPlayer
- Add a 1.2s cross-type cooldown so a rapid lid close->open no longer
plays lock-then-unlock chimes as a doubled sound (the per-type
throttle never covered this case).
- Bump per-type throttle 0.25s -> 0.6s.
- Reset throttle state when enableLockSounds is toggled back on, so the
first chime after re-enable is never suppressed by a stale timestamp.
StatsManager
- Shorten notchCloseStopDelay 3.0s -> 1.0s so the monitoring timer is
invalidated sooner after the user closes the notch, freeing the
main-thread tick budget for animation work.
