- baileys-event-stream.ts: Add null check for buffer item in priority insertion
- baileys-logger.ts: Handle 'silent' log level and fix JID sanitization
- cache-utils.ts: Fix type incompatibility in global cache with any type
- logger-adapter.ts: Add nullish coalescing for level mapping and fix console type cast
- prometheus-metrics.ts: Rename private 'metrics' property to 'metricsMap' to avoid conflict with method
- trace-context.ts: Store baggage header in variable before accessing to fix undefined check
