isep-doctor：講出這台的 ISEP plugin 有沒有真的載入（inkstone/ISEP#150）

根因不是「Desktop 不跑 hook」：Desktop 1.52386.0／CC 2.1.266 內實測專案
PreToolUse hook 照擋。真正斷的是 ~/.claude/settings.json
extraKnownMarketplaces.inkstone.source 多了 path，CC 把它當 git 抓取欄位，
marketplace 被忽略 ⇒ isep@inkstone「Marketplace inkstone not found」，
59 支閘在 CLI 與 Desktop 一起失效，而且沒有任何閘講得出來。

本支從 plugin 外面查（claude plugin list --json ＋ settings 對 known_marketplaces），
點名多出的欄位並印出一行修法。迴歸測試 scripts/test-isep-doctor.sh 5/5。

假設：修 ~/.claude/settings.json 是 leo 的個人設定，由 leo 親手執行，本 commit 不動它。
