Agent Skills: format-and-commit

Chains Korean code-comment formatting and conventional-commit creation into a single PR-prep flow. Use when the user wants to add comments AND commit in one pass — triggered by "주석 달고 커밋", "PR 준비해줘", "주석 정리하고 커밋", "format and commit", "comment then commit", or any phrasing that pairs commenting with committing on recently changed code. Delegates to `dmk-oneteam:format-code-comments` first, gates on user approval, then delegates to `dmk-oneteam:git-commit`. Never runs `git add .`, `git add -A`, or `git commit -a`.
