Merge PR

Sequence a repository's pre-merge gates fail-closed, run its own pre-merge worklist, then merge. Works in any repository with an authenticated gh.

Repository conventions come from .tailrocks/pr.md when present — format and precedence are defined with tailrocks-create-pr. This skill reads its ## Checks, ## Blast radius, ## Before merge, and ## Merge sections; without the file, GitHub's branch protection, the repository's merge settings, and this skill's defaults govern.

Arguments

• PR — PR number (defaults to the current branch's PR).
• --no-poll — do not wait on pending CI; stop and report instead.
• --admin <check> — authorize bypassing one named failing check (still needs the high-blast-radius confirm).
