RG-01: Retrieval Governance Layer integration tests.

Verifies that:
1. search() returns governance dict (results + _governance_report + _escalation_queue)
2. Each result carries _governance metadata
3. Sacred memories are BLOCKED for unauthorized actors
4. Private memories are BLOCKED for mismatched actors
5. arif_memory_recall(search) surfaces _governance_report + _escalation_queue
6. arif_memory_recall(recall) returns _governance verdict

Namespace: TEST ONLY
Never mutates production memory.
