chore(state): STATE.a2ml — 7b-3 bridge done, Task-E done, 99% complete

- 7b-3: closed (commit 9887638 — two-path write, canonical names, 8 tests)
- Task-E: closed (T2 — 48 call-site fixes + solver_integrity debug-repr fix)
- container.rs: closed (T2 — 848 LoC Podman+bwrap)
- completion-percentage: 96 → 99
- double-loop-feedback.completion: 80 → 100
- maintenance-status: 137/137 tests
- blockers updated: only seam test + BoJ Zig adapter remain
