Agent Skills: format-code-comments

Adds Korean inline comments, documentation comments (TSDoc / Google-style docstring), and section comments to TypeScript and Python code before a PR. Analyzes git diff against a chosen base branch, expands scope to full functions and classes that contain changes, reviews existing comment quality, presents an approval plan, then writes. Use when the user says "주석 달아줘", "PR 전 주석 정리", "comment 추가", "코드 문서화", "docstring 작성", "JSDoc 추가", or describes wanting comments on recently changed code. Works on entire files or specific functions/sections. Do NOT use for code review, refactoring suggestions, or documentation outside source files.
