Root cause: Tests marked @pytest.mark.serial were still being parallelized in CI because pytest-xdist doesn't respect custom markers by default. With host-level telemetry batching (PR #718), tests running in parallel would share the same TelemetryClient and interfere with each other's event counting, causing test_concurrent_queries_sends_telemetry to see 88 events instead of the expected 60.

Now explicitly clear the _flush_event flag in both setup (before test) and teardown (after test) to ensure clean state isolation between tests.
