+E2E Test Configuration — Hardened Test Infrastructure
+======================================================
+
+Design Principles:
+    1. No module-level mutable state (VirtualClock is a fixture, not a global)
+    2. No sys.modules poisoning (Qdrant mock via monkeypatch)
+    3. Unified fixture loading from a single source of truth
+    4. Global timeout to prevent infinite hangs in mocked loops
+    5. Deterministic loop termination via MaxIterationGuard
