- Add pytest and pytest-asyncio as optional dev dependencies
- Configure asyncio_mode=auto and pythonpath=[src] in pyproject.toml
- Write three tests at the poll() seam:
* single-page response publishes all Flights and returns the count
* paginated response follows link:rel=next and publishes all pages
* HTTP error from raise_for_status() propagates out of poll()
Tests use injected stub HTTP session and mock Kafka engine;
no real network or broker required.
