fix: add thread-safe synchronization to EnrollmentTracker shared state
All mutable state fields accessed from multiple threads (timer callbacks, ImeLogTracker events, EspAndHelloTracker events, desktop detection, background Task.Run) are now protected by a single _stateLock. Key fixes: - TryEmitEnrollmentComplete: atomic guard-check-and-claim prevents double enrollment_complete emission (the most critical race condition) - RecordSignal: List<string> mutations are now thread-safe - NotifyDesktopArrived: atomic check-and-set prevents duplicate processing - CollectDeviceInfo: _enrollmentType/_skipUserStatusPage writes are visible to concurrent readers immediately after lock release - OnHelloCompleted/OnWaitingForHelloSafetyTimeout: consistent multi-field reads prevent wrong branch selection - SummaryTimerCallback: _stateDirty flag and _stateData serialization are synchronized to prevent corrupted state persistence - EmitAppTrackingSummaryIfChanged: hash comparison is atomic to prevent duplicate summary events Lock discipline: all lock sections contain ONLY field reads/writes — no _emitEvent, _logger, timer operations, or external callbacks. This guarantees no deadlocks and microsecond-level contention. https://claude.ai/code/session_01EWzmYXFmXUaPpeksi6WGKZ
