feat(python): implemented host tool event normalization and error checks

- Added `_normalize_host_tool_event` to `RpcClient` to remap transport tool events to executed host tools.
- Updated worker tool-end handling to verify `is_error` is false before marking terminal actions complete.
- Added test coverage in `test_client.py` and `test_worker.py` for host tool event normalization and errored review submission behavior.
