## 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
