"""Shared test fixtures: framework-loop isolation between tests.

The framework runs one asyncio loop for the whole process. Tests
create tasks, resources, and timers on it; without cleanup those leak
into the next test. This autouse fixture closes the guest loop after
every test (cancelling pending work) so each test starts with a fresh
loop.
