feat(pr-watch): 回報 PR 現況，並在它結束時清掉工作樹
開發者要能隨時問一句「這個 PR 現在怎麼樣、我還有什麼要做」。回報 PR 狀態、還有幾則 留言沒處理、工作樹在哪、裡面有沒有沒提交的東西，以及固定列舉值的 suggestedAction ——用列舉值而不是一段文字，呼叫端才能程式化判斷。 一次性、無狀態：不做變化偵測。已處理的判定基準是 Gitea 上的 +1 與 resolve，那個狀態 不在本機記憶裡，所以一份現況快照就足以回答「還有沒有事要做」，不必跟上次比較，也就 不必留任何游標或狀態檔。不做常駐程序也不做 daemon，排程交給呼叫端。 只通知，不動手：偵測到未處理留言只給建議，不自動執行 /sdlc-fix——流程不該被模型自動 觸發，而 /sdlc-fix 要求「不確定時詢問使用者」，非互動模式下那個詢問無處可去。 四種狀態的處置不一致，所以表格驅動測：merged 與 closed 終止並清理；open 繼續監看； draft 繼續監看且**不清理**——被退回草稿代表還要繼續改，這時候那棵工作樹更需要留著。 議題 #41 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

/**
|
||||
* 回報 PR 現況，並在它結束時清掉工作樹。
|
||||
*
|
||||
* 這一支的價值在**四種 PR 狀態各自的處置**：merged 與 closed 是終止狀態，工作樹清掉；
|
||||
* open 繼續監看；draft 尤其要盯住——被退回草稿代表還要繼續改，這時候那棵工作樹更需要
|
||||
* 留著，清掉它等於把人做到一半的環境收走。
|
||||
*
|
||||
* 另外兩件事各有測試：建議動作是**列舉值**（呼叫端要程式化判斷，不是去讀一段文字），
|
||||
* 以及清理的守門（有未提交變更就擋下，絕不 `--force`）。
|
||||
*
|
||||
* 一次性、無狀態：不與上次的結果比較，也不讀寫任何游標或狀態檔——「已處理」的判定
|
||||
* 基準是 Gitea 上的 `+1` 與 resolve，現況快照本身就足以回答「還有沒有事要做」。
