w-fix-push

Invocation requests fix → smallest matching check → commit → push for the named issues. This is not /w-ship (no PR, not the full pre-push suite) and not a merge or deploy. Follow git publish.

1. If creating a new branch, git fetch origin then git switch -c <name> --no-track origin/main first — never skip fetch, never a stale local main. Address the reported errors, warnings, or feedback (lint, types, tests, reviews).
2. Run the smallest existing check that matches the failure. Never the full pre-push suite.
3. Commit intended paths only, then push the inspected upstream. Do not open a PR unless the user asked /w-pr or /w-ship.
