PR Review Fixer

Fetch unresolved review threads on a change request (CR), validate each issue, create a fix plan, implement fixes, and verify CI checks pass (tests, lint, build).

This skill is forge-aware: the repo may be on GitHub (gh) or GitLab (glab). It does not hard-code either CLI — it follows the shared operation contract and the adapter for whichever forge the repo uses.

Forge setup (do this first)

1. Read ~/.claude/forge-adapters/CONTRACT.md — it defines the neutral terms (CR, thread, note, <id>) and the operations this workflow calls.
2. Run PREFLIGHT to determine FORGE and confirm the CLI is authenticated. If not, stop and tell the user how to authenticate.
3. Read the matching adapter ~/.claude/forge-adapters/<FORGE>.md. Every concrete command below comes from that adapter's ## OPERATION section — do not improvise gh/glab commands.
