Ahmed Darrazi 39fd8ca1ea feat(spec-119): baseline compare drift cutover
- Enrich drift findings evidence_jsonb for diff UX (summary.kind, refs, fidelity, provenance)

- Add baseline policy version resolver and contract asserts

- Remove legacy drift generator + DriftLanding surfaces

- Add one-time cleanup migration for legacy drift findings

- Scope baseline capture/landing warnings to latest inventory sync

- Canonicalize compliance scheduledActionsForRule drift signal
