fix(clients): repair Python & Rust tests, add container test orchestration

- Python: fix wire protocol test method names (bool_val -> bool, etc.)
- Python: make integration tests and example fully async with pytest-asyncio
- Rust: add tokio dev-dependency and convert integration tests to async/await
- Rust: update ping_test example to async
- Nim: remove committed ELF build artifact
- Docker: add BARADB_HOST/BARADB_PORT env vars to test containers
- Docker: fix docker-compose.test.yml usage (remove --abort-on-container-exit)
- Add scripts/test-clients.sh for sequential client test runs
- Remove docker-compose.test.yml from .gitignore so it is tracked
- Fix repository URLs in Python and Rust READMEs
