feat(02-05): annotate 21 orphan ACs with pending-phase-N status

Reconciles all orphan ACs from Plan 02-04 SUMMARY with explicit phase
deferred annotations so the ac-traceability --check gate passes in CI.

Phase mapping applied:
- Phase 3 (SAFE/VERIFY): AC-3.5, AC-4.5, AC-5.1, AC-5.3, AC-8.2, AC-NEW-4, AC-NEW-6, AC-NEW-8
- Phase 4 (FDR/VPR):    AC-2.1b, AC-3.1, AC-3.2, AC-4.2, AC-8.1, AC-8.3, AC-8.4, AC-8.5, AC-8.6
- Phase 5 (MAVOUT):     AC-6.1, AC-6.2, AC-7.1, AC-7.2

python scripts/gen_ac_traceability.py --check now exits 0.
