"""Root conftest — auto-skip tests that require external infrastructure.

Tests that import or call into Qdrant, OAuth config, or a live MCP server
will fail in CI where those services aren't available.  Rather than adding
skip markers to every file, this conftest inspects the test's module path
and required env vars, then skips automatically when the infrastructure
isn't present.
