* feat(signal): add RetryReason enum and MAC error-based session recreation
* feat(signal): add identity change detection with automatic session clearing
* fix(signal): integrate identity change detection with pkmsg decryption
This completes the identity change detection implementation by actually
calling saveIdentity() during pkmsg decryption, which is CRITICAL for
the feature to work.
Changes:
- Add extractIdentityFromPkmsg() function that parses PreKeyWhisperMessage
protobuf to extract sender's identity key (33 bytes)
- Call saveIdentity() BEFORE decryption in decryptMessage() for pkmsg type
- Log when identity change is detected
Flow:
1. Receive pkmsg from sender
2. Extract identity key from PreKeyWhisperMessage protobuf
3. Call storage.saveIdentity() which compares with stored key
4. If key changed → session is cleared atomically
5. Decryption proceeds with re-established session
This matches WhatsApp Web's behavior where extractIdentityKey is called
before handleNewSession (GysEGRAXCvh.js:40917, 48815).

* lid-mapping: fix build error on NPM
* message-retry: fix proto import
* Add message retry manager for session recreation and caching
Introduces a MessageRetryManager to cache recent sent messages and manage automatic Signal session recreation for failed message retries. Adds new config options to enable these features, integrates retry manager into message send/receive logic, and provides periodic cache cleanup. Improves reliability of message delivery and retry handling.
* Add buffer timeout and cache limit to event-buffer
Introduces a buffer timeout to auto-flush events after 30 seconds and limits the history cache size to prevent memory bloat in event-buffer.ts.
* Add session validation to SignalRepository
Introduces a validateSession method to SignalRepository for checking session existence and state. Updates message retry logic to use the new validation, improving session recreation handling and retry management.
* Improve message retry management and tracking
Refactored message retry manager to use LRU caches for recent messages and session history, added retry counters and statistics tracking, and implemented phone request scheduling. Updated message receive and send logic to mark retry success and pass max retry count. Removed periodic cleanup logic in favor of cache TTLs for better resource management.
* lint fix
* Use validateSession for session checks in message send
Replaces direct session existence checks with the improved validateSession method, which also checks for session staleness. Adds debug logging for failed session validations to aid troubleshooting.
* Delete src/Utils/message-retry.ts
