[CLAUDE] Docs: S44 monthly drift audit + AI_INFRA bundle 06-01 adopt

Cadence audit (2026-06-01), docs-only -> CI-skip. investigator-codebase
drift scan (ground-truth from disk) -> em main patch. No code touched,
154 test unchanged.

Drift fixes (42 count corrections): 40->42 mig, 84/59/55/47->91 tables,
130/111->154 test, 52/49->56 gotcha across CLAUDE.md, docs/CLAUDE.md,
ef-core-migration + dependency-audit skills, schema-diagram, database-guide.
schema-diagram migration table extended Mig 17-42; ef-core history Mig 27-42;
detailed-section gap (Mig 27-42 modules) flagged explicit (deferred, not silent).

AI_INFRA bundle 06-01 (federated, full scope):
- A: RAG T1/T2 auto-ack
- C: hygiene 7/7 agent-mem L1 <=16KB; "25KB"->"~30KB tiered" wording x7
- D: #4 self-sustaining adoption-report step -> /session-end Phase 6.3
- E/F: report + ledger -> docs/governance/

Carry-over .mcp.json + BROADCAST-05-29 left untouched (concurrency rule).
