Add module-scoped autouse fixture `reset_all_singletons` in
tests/integration/conftest.py that resets all global singletons
between test modules:
- _qdrant_client (vector/qdrant_client.py)
- _embedding_service, _bm25_service (embedding/service.py)
- _provider (providers/registry.py)
- _vector_sync_state with memory streams (app.py)
- _tracer (observability/tracing.py)
- _registry (auth/client_registry.py)
- _token_exchange_service (auth/token_exchange.py)
This fixes anyio.WouldBlock errors that occurred when running the
full integration test suite together. The errors were caused by
stale singleton state holding references to dead event loops or
closed memory streams from previous test modules.
Results:
- Before: 22 passed, 26 errors (WouldBlock), 12 failed
- After: 48 passed, 25 skipped, 1 failed (unrelated timeout)
