Commenting '@claude <instruction>' on a PR runs headless Claude Code on the
PR branch (subscription auth), pushes the resulting commit — re-running the
PR checks — and replies with a summary. Owner-only trigger; runs unsandboxed
inside the ephemeral runner container per explicit maintainer sign-off.
