v1.0.30: fix sync loop root causes + icon redesign

Three root causes found via live logcat on device:

1. concurrent refresh() race: onStartCommand received twice causes two
   refresh() coroutines to run in parallel, doubling FileObserver and
   catchupScan registrations. Fixed with Mutex.withLock on refresh().

2. catchupScan no cooldown: catchup syncs write files but never set
   syncCooldownUntil, so every written file immediately re-triggers
   onChangeDetected. Fixed by setting cooldown before enqueue and
   watching work completion same as onChangeDetected does.

3. CancellationException caught silently: exception handler
   catch(_: Exception) was catching CancellationException and resetting
   cooldown to 0L, re-opening the loop. Fixed by rethrowing
   CancellationException and setting 60s cooldown on other errors.

Icon: interlocked rings (blue/red/green/orange) with sync arrow at
center, pure black background — matches reference image.
