v1.5.5

Fixed

• Worker Lock Leaks: Fixed lock not being released when config validation fails or worker thread fails to start, which could block queue processing.
• MTBF Calculation: Fixed incorrect Mean Time Between Failures calculation that measured time between outage starts instead of actual uptime between failures.
• Outage End Not Recorded: Circuit breaker _close() now records outage end in history, fixing incomplete outage metrics (MTTR, MTBF, availability).
• MTTR Crash Protection: Added defensive null check on outage duration before summing, preventing crash on corrupted data.
• Reconciliation Scheduler Locking: Added fcntl.flock() file locking to prevent concurrent processes from corrupting scheduler state.

Improved

• Standardized queue operation logging via shared.log
• PlexClient now supports context manager (with PlexClient(...) as c:)
• Reconciliation batch size configurable via reconcile_batch_size
• Plex userRating extracted for metadata comparison
• Module exports aligned with actual usage
