Merge pull request

Carry the current request's change through a pull request, verified merge, and safe local cleanup. Complete the necessary commit, synchronization, publication, and PR work without depending on other skills.

Start from current remote truth. Preserve unrelated work, commit only the request's changes as logical Conventional Commits, resolve the named base or the remote's advertised default branch, and create or reuse a ready-for-review pull request based on its fetched state. If the change or its pull request is already merged, verify and report that outcome instead of creating another one.
