Resolve Review Comments

Take every review comment on a pull request to a resolved end state: each one is either fixed (code changed, with a test) or rebutted (a one-line reason it is not a defect), then replied to and its thread resolved. No thread is left open and no finding is actioned on faith.

A review comment is a claim, not an instruction. Bots (Codex, Copilot, Gemini) are confidently wrong often enough that every finding earns its verdict from the code, the spec, the tests, and the permission model, never from the comment's own say-so.

1. Gather every thread

Resolve the repo (gh repo view --json nameWithOwner) and the PR number (from the argument, or gh pr view --json number for the current branch). Pull all three comment surfaces (reviews, inline review threads, general issue comments) and the PR's commit range. See references/gh-mechanics.md for the exact gh api and GraphQL calls; you need it whenever you touch the GitHub side.
