Commit Message

Add duplicate message detection for spam filtering

Implement duplicate message detection to identify spam from users
sending the same message repeatedly. Uses LRU cache with 10K user
limit to prevent memory exhaustion and O(1) hash-based tracking.

Features:
- Configurable threshold for number of duplicates to trigger spam
- Time window for tracking duplicate messages
- Automatic cleanup of expired entries
- Thread-safe implementation with mutex protection
- LRU eviction when user limit is reached

Configuration:
- --duplicates.threshold: number of identical messages (default: 0, disabled)
- --duplicates.window: time window for detection (default: 1h)

Includes comprehensive tests for functionality, concurrency, and edge cases.
