feat(lid-mapping): enhance with enterprise-grade features
Major improvements to LIDMappingStore: Configuration (BAILEYS_LID_* env vars): - BAILEYS_LID_CACHE_TTL_MS: Cache TTL (default: 3 days) - BAILEYS_LID_MAX_CACHE_SIZE: Max cache entries (default: 50000) - BAILEYS_LID_BATCH_SIZE: Batch size for bulk ops (default: 100) - BAILEYS_LID_RETRY_ATTEMPTS: Retry attempts (default: 3) - BAILEYS_LID_RETRY_DELAY_MS: Retry delay (default: 1000) - BAILEYS_LID_METRICS: Enable Prometheus metrics - BAILEYS_LID_DEBUG: Enable debug logging New Features: - Comprehensive statistics tracking (getStatistics()) - Cache warming capability (warmCache()) - Cache management (clearCache(), getCacheInfo()) - Batch operations for bulk mappings - Retry logic with exponential backoff - Custom error types (LIDMappingError, LIDMappingErrorCode) - Proper resource cleanup (destroy()) - hasMappingForPN() for existence checks - deleteMapping() for cache invalidation Enterprise Patterns: - Environment variable configuration - Statistics and metrics integration - Retry with exponential backoff - Destroyed state protection - Batch processing for performance - Detailed error codes and messages
