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

What：
- 修正 skills/models/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 0.2.6 進到 0.2.7。

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 cli 技能組的 models 技能，屬盤點各 CLI 可用模型與能力標籤的功能。

 name: models
-description: List every model usable by each installed AI CLI (claude, codex, copilot, antigravity, kiro) and attach capability tags from references/model-tags.md. Syncs the tag table to $JSC_HOME/model-tags.tsv via tools/model-tags.sh, so jsc-sdlc gates are enforced in code. States each SDLC stage's required tags: plan and analyze need reasoning-max, implement needs coding, maintain any. Resolves each stage's preferred model chain via tools/model-config.sh (project .jsc/models overrides $JSC_HOME/models.conf), for switch suggestions only. Use when checking model fitness, inventorying models, or reviewing stage gating; not for switching models or editing the config files.
