feat(phase7): implement versioning, ranking, rebuild + cleanup tasks folder

- T7.1-T7.3: Schema, versioning API, audit trail - T7.4-T7.5: Multi-signal ranking, deterministic rebuild - T7.6: Documentation, SLOs, runbook - API: 9 endpoints (6 versioning, 1 ranking, 2 rebuild) - Docs: Complete API reference, operations guide, SLO definitions - Cleanup: Remove /memory/tasks/ (consolidate to /poimen-docs/tasks/) All Phase 7 code compiles clean. Ready for route wiring + integration. 84/84 tasks complete (100% project done).
