Implement performance optimizations including caching layer and query optimizations.

Current Performance Gaps

Database queries not optimized (no indexes on frequently queried columns)
No caching for repeated regex patterns
Message history lookups are O(n) without proper indexing
Compiled regex patterns not cached between requests

Implementation

Add database indexes for:
- message_history: chat_id, timestamp
- bot_replies: target_message_id, chat_id
Implement LRU cache for:
- Compiled regex patterns
- Frequently accessed message history
- User rate limit counters
Optimize sed command parsing with caching
Add prepared statements for common queries

Configuration

New environment variables:

CACHE_ENABLED - Enable caching (default: true)
CACHE_MAX_SIZE - Maximum cache entries (default: 1000)
CACHE_TTL_MS - Cache TTL in milliseconds (default: 300000)

Benchmarks

Establish performance benchmarks:

Command processing time < 100ms average
Database query time < 10ms average
Worker pool queue depth monitoring

Testing

Performance regression tests
Load testing with simulated traffic
Memory usage monitoring
