feat: implement periodic session cleanup for inactive/orphaned sessions
Implements automatic cleanup of Signal sessions to prevent database growth:
**Configuration (environment variables):**
- BAILEYS_SESSION_CLEANUP_ENABLED=true (default: true)
- BAILEYS_SESSION_CLEANUP_INTERVAL=86400000 (24h default)
- BAILEYS_SESSION_CLEANUP_HOUR=3 (3am default)
- BAILEYS_SESSION_SECONDARY_INACTIVE_DAYS=15
- BAILEYS_SESSION_PRIMARY_INACTIVE_DAYS=30
- BAILEYS_SESSION_LID_ORPHAN_HOURS=24
**Cleanup rules:**
1. Secondary devices (Web, Desktop): inactive > 15 days
2. Primary devices: inactive > 30 days
3. LID orphans (no PN mapping): > 24 hours
**Safety guarantees:**
- Does NOT affect WebSocket connections
- Does NOT cause message loss (Signal Protocol auto-recreates sessions)
- Runs in low-traffic hours (3am default, configurable)
- Atomic transactions (all-or-nothing)
- Comprehensive logging and statistics
**Implementation:**
- src/Signal/session-cleanup.ts: Core cleanup logic
- src/Defaults/index.ts: Configuration defaults
- src/Socket/socket.ts: Integration and lifecycle management
**Note:** Activity tracking not yet implemented (required for time-based cleanup).
Current implementation only cleans LID orphans (sessions without PN mapping).
