granthi-review v1: estate-wide AI code review service

Webhook-driven central review service for Granthi forges: HMAC-verified
push/pull_request webhooks, per-repo serialization with global LLM
concurrency 1, shre-router powered rubric review (8 axes, strict JSON,
tolerant extractor + retry), commit statuses + PR scorecard comments,
sqlite attribution ledger with Co-Authored-By trailer parsing, per-repo
HTML history dashboard, nightly per-agent digests, fail-open-with-
visibility when the router is unavailable.

Posture: BLOCK on confirmed critical/high correctness+security findings;
admin merge is the human override.
