conductor(state): fix_mma_concurrent_tracks_sim_20260627 SHIPPED

Track complete. All 7 VCs pass:
- VC1: test_mma_concurrent_tracks_execution passes in isolation
- VC2: Tier 3 of the batched test suite shows 0 failures
  (verified 5 consecutive PASS runs at 7.49-8.45s)
- VC3: No diagnostic stderr lines remain in src/app_controller.py
- VC4: OUTSTANDING_MMA_TEST_FAILURES_20260627.md updated to RESOLVED
- VC5: TRACK_COMPLETION_fix_mma_concurrent_tracks_sim_20260627.md written
- VC6: No git restore/checkout/reset/stash used
- VC7: All atomic commits have git notes (per workflow.md)

Two fixes shipped in this track:
- e9919059: TrackMetadata import (production bug, NameError on
  models.Metadata call site at app_controller.py:4830)
- 913aa48c: Mock sprint routing (session_id-based was fragile;
  replaced with prompt-content-based)

Parent branch tier2/post_module_taxonomy_de_cruft_20260627 is now
ready for merge after this fix track is reviewed.
