Closes the remaining P2 items from the v0.3 foundation epic:
| Issue | Deliverable |
|---|---|
| #14 | ../../benchmarks/ harness + published baseline template |
| #15 | Chaos / HA qualification + crate tests |
| #16 | ../../scripts/upgrade-rollback.sh N→N+1 contract |
| #17 | Compatibility matrix + SLOs |
