## 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

Implements the HealthMonitor class for tracking connection health:
- Tracks connection states per stream (active, stale, disconnected)
- Records events and calculates throughput (events/second)
- Detects stale streams (no events for configurable threshold)
- Exposes Prometheus-compatible metrics endpoint (/metrics)
- Provides HTTP health endpoints (/health, /ready, /live)
Exports: HealthMonitor, HealthReport, HealthStatus, StreamHealth, StreamStatus
Tests: 47 comprehensive unit tests covering all functionality

Implement EventPublisher class for publishing trade events to Redis
Streams, enabling decoupled downstream processing. Key features:
- EventPublisher wrapping Redis Streams XADD/XREADGROUP commands
- Single and batch publishing with configurable max stream length
- Consumer group management (create/ensure)
- Event reading with pending entry recovery
- Acknowledgment helpers for exactly-once semantics
- Stream info and trimming utilities
- Full TradeEvent serialization/deserialization
