feat(pr): security-hardened review-response run — pr-respond body (U5)
Implements the fix-or-disagree agent loop behind pr-respond: batched one-run-per-cycle over actionable threads (filtering resolved/outdated/ self/bot), with prompt-injection delimiting of untrusted comment bodies, viewer-authenticated anti-spoof markers, a pre-push secret scan, fast- forward-only push (no force-push path) with non-ff abort+re-batch, reply+ resolve, commit-last thread-state persistence with marker+SHA crash recovery (R15), and an iteration cap on responseRounds (R8). GitHub/git/ agent ops injected; engine stays dashboard-import-free. Adds GraphQL getPrReviewThreadsDetailed + getViewerLogin to the client. 23 tests.
