feat(coupling): Phase 5 — 53-case test suite (CP_01–CP_49 + TestCpShort, 7 tiers)

Unit (CP_01-08): file derivation, heat modifier, pair canonicalisation Integration (CP_09-18): provider upserts, re-runs, counts, ref column E2E (CP_19-25): full seeded scenarios, min_co filter, top limit Performance (CP_26-32): timing bounds under realistic load State (CP_33-38): idempotency, stale-row purge, incremental updates Security (CP_39-44): injection strings, repo isolation, unicode paths Stress (CP_45-49): MAX_PAIRS cap, mass-commit exclusion, BFS cap

All 53 tests pass.
