"""Shared test configuration — sets env vars ONCE before any test module runs.

The env must be consistent for the whole pytest session: server.py freezes
COLLECTION_NAME/QDRANT_URL at import time, while the integration fixture
reads os.environ at fixture time. If any test module mutates os.environ after
that (test_server.py used to set COLLECTION_NAME='test'), the fixture creates
a different collection than the one server functions query → 404.
Keep all env wiring here so import order no longer matters.
