Mention-triggered reviews that explicitly ask for a verdict now submit a
real APPROVE/REQUEST_CHANGES through publish_review; auto-reviews stay
advisory (COMMENT). Authorization is enforced in code: publish_review
honors a verdict only when the dispatching webhook set verdict_requested,
which only the explicit-mention path does.
- request_pr_review gains instructions (forwarded verbatim into an escaped
requester_instructions data block) and request_verdict
- self-review guard downgrades verdicts on Open SWE-authored PRs; stale
APPROVEs are best-effort dismissed when later findings land
- new PullRequestVerdictGuardMiddleware blocks gh pr review
--approve/-a/--request-changes/-r, gh api, and curl verdict fallbacks on
both the coding-agent and reviewer graphs
- shared escape helper moved to agent/utils/prompt_data.py
