* - Add S06 relay-only test case for testing message propagation without a store.
- Update `wrapper_helpers` for clearer event type handling and type annotations (`Optional[...]` usage).
- Simplify `get_node_multiaddr` to retrieve addresses via `get_node_info_raw`.
- Refactor `wrappers_manager` to adjust bindings path to `vendor` directory and add `get_node_info_raw` method.
- Update `.gitignore` to exclude `store.sqlite3*`.
* Refactor S06 relay-only test: replace try-finally blocks with context managers for clarity and conciseness.
* Migrate S06 relay-only test to `test_send_e2e.py` and refactor with `StepsCommon` for reusability.
