perf(doi): fingerprint-based DB cache for DoI results
Adds doi_cache table (migration k8f9a0b1c2d3). Results are stored after
each evaluation and reused on subsequent requests when the fingerprint
matches. Fingerprint covers repo.updated_at, latest TPSC snapshot_at,
latest goal updated_at, and mtime of SCOPE.md / CLAUDE.md / tpsc.yaml.
Behaviour:
- Summary (warm cache, nothing changed): ~0.4s (was 0.9s)
- Summary (one repo stale): ~0.9s (only stale repos recomputed)
- Single repo (cache hit): ~0.2s (was 40s for full check)
- Single repo ?force_refresh=true: ~2s (full C7/C13 subprocess check)
Total journey: 108s (original) → 6s → <1s → 0.2s (cached single repo)
