- Add pydantic-settings dependency
- Create centralized config.py with nested settings groups:
- DatabaseSettings: PostgreSQL connection validation
- RedisSettings: Redis connection with defaults
- PolygonSettings: RPC endpoints with fallback support
- PolymarketSettings: WebSocket URL and optional API key
- DiscordSettings: Optional webhook for alerts
- TelegramSettings: Optional bot token/chat ID for alerts
- Implement singleton pattern with get_settings() and LRU cache
- Add redacted_summary() for logging config without exposing secrets
- Support .env file loading via python-dotenv
- Add comprehensive test suite (26 tests)

## Changes
### test_get_market_not_found
- Updated test to expect `RetryError` instead of `ClobClientError`
- The `get_market` method uses the `@with_retry()` decorator, so when
the underlying API call fails repeatedly, it raises `RetryError`
wrapping the original exception
- Removed unused `ClobClientError` import
### test_start_and_receive_trades
- Replaced `MagicMock` with a proper `MockWebSocket` class that
implements the async iterator protocol correctly
- `MagicMock` was passing `self` as an extra argument when calling
`__aiter__`, causing "takes 0 positional arguments but 1 was given"
- Removed unused `MagicMock` import

Add sniper cluster detection system that identifies wallets exhibiting
coordinated "sniper" behavior - consistently entering markets within
minutes of their creation.
Key features:
- SniperDetector class using DBSCAN clustering algorithm
- Tracks wallet entries across markets with timing analysis
- Feature vector: market hash, entry delta, log position size
- Identifies clusters of wallets with similar timing patterns
- Generates SniperClusterSignal for detected cluster members
- Configurable entry threshold (default 5 minutes), cluster size, DBSCAN params
- Confidence scoring based on cluster size, entry speed, market overlap
Also adds:
- SniperClusterSignal model to detector/models.py
- scikit-learn and numpy dependencies for ML clustering
- 27 comprehensive tests covering clustering logic and edge cases
