fix(frontmatter): 修正 commit 技能 SKILL.md frontmatter 的 YAML 純量語法錯誤

What：
- 修正 skills/commit/SKILL.md frontmatter 裡 description 欄位的 YAML 語法錯誤。
- 整串 description 加上單引號，內部撇號改寫成兩個單引號，內容文字一個字都沒變。
- 同步更新 plugin.json、.claude-plugin/plugin.json、.codex-plugin/plugin.json 三個 manifest 版本號，從 0.1.3 進到 0.1.4。

Why：
- description 內含「冒號加空白」，屬於未加引號的 YAML plain scalar，違反 YAML 語法規定。
- Antigravity 解析 frontmatter 時當場中斷，整支技能被靜默丟棄，沒有任何錯誤訊息；磁碟上 34 支技能，Antigravity 只認得 28 支。
- 準則要求 description 用英文撰寫，不能把「: 」改成全形冒號迴避語法問題，只能加引號修正。

How：
- 整串 description 值加上單引號，內部撇號寫成兩個單引號跳脫，其餘字元不動。
- 用 git show HEAD: 取出改前的原始值，把改後的單引號純量還原後做字串相等比對，確認逐字相同、字元數一致。
- 執行 ste100-lint.sh、check-behaviors.sh、lint-frontmatter.sh 三支檢查腳本，退出碼皆為 0；git diff --numstat 顯示只動了 frontmatter 那一行。

Who：
- 本次修到 git 技能組的 commit 技能，屬分組 commit 訊息並依 What/Why/How/Who 撰寫本文的功能。

-description: Group all pending file changes by conventional type and feature, then commit each group as {type}({scope}): {message}. Before committing, sweep the working tree with jsc-hooks/hooks/comment-scope.sh so no comment carrying document tracking information enters a commit. Message style is full (What/Why/How/Who), brief (one line from git diff), or custom, chosen via decision tree. Once the commits land, an open PR on the current branch gets its title, description, and prerequisite dependency calibrated through jsc-git:pr. Use whenever changes must be committed; not for push or PR creation.
