feat: implement TTL cache for message deduplication and remove debug logging
- Replace manual map-based deduplication with jellydator/ttlcache/v3 - Add automatic cache eviction with 30-second TTL to prevent memory bloat - Implement proper cache lifecycle management (start/stop) - Remove emoji debug logs from bridge system and XMPP client - Clean up verbose logging while maintaining essential error handling - Update bridge interface method names for consistency 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
