fix(assistant): 讓執行路徑走錯與警示原因都看得見

兩支腳本開跑就檢查自己的執行路徑，監控頁的摘要表與最新一輪那一塊補上
「警示來源」。

兩件都是實測之後補的。用全新的 CLI 行程跑，代理人會把工具路徑解回外掛
快取那一份，不是指定的工作樹那一份。原本的對策只在技能說明書裡寫明禁

組確切路徑，走錯就被靜靜擋掉，那一輪不寫心跳，外面只看得到心跳過期。
另一頭，沙箱跑出來的摘要列是「警示、四項全過、待人處理 0」，讀的人看
不出警示哪來。查過不是缺陷：四項來源都讀得到，是讀到的內容有警示。摘
要表的用途本來就是一眼看出從哪一輪開始壞，少了原因那一欄就做不到。

巡檢與排程兩支腳本開跑時先比對自己是不是從 current 底下被叫起來的，不
是就往 stderr 印一行警告，點名實際路徑、應該用的路徑與理由。刻意只警告
不中止：從工作樹直接跑腳本是開發時的正當用法，中止會把那條路擋掉，真
正的失敗本來就發生在權限閘門那裡。摘要表從四欄加到五欄，最新一輪那一
塊也補一列，值取每一處設警示時收下來的短理由，多個用頓號串，沒有就寫
「無」。腳本裡每一處把判定改成警示的地方，一律改走同一支函式順手收下
理由，collect 的輸出多印一行 warn_sources。技能主文、行為清單與監控頁
範本跟著寫明這兩件事。

功能範圍是助理的一輪巡檢與系統排程安裝。

 **Never build a tool path out of the base directory the CLI hands you in the skill prompt.** That directory points into the plugin cache and carries a version segment, and the permission gate allows exactly the four paths above and nothing else. A cache path is therefore refused silently: the round stops on a permission prompt nobody can answer, records nothing, writes no heartbeat, and the refusal looks exactly like a broken tool. Read the paths off this table every time — not off the prompt, not off a previous transcript, not off `crontab -l`.
 
+Both scripts check this for themselves: run from anywhere outside `$JSC_HOME/current`, they print a `[WARN]` line on stderr naming the path they were started from and the path they should have been started from, and then carry on. That line means this round is on the wrong path — quote it, fix the path, and do not treat the round's success as proof that the path was fine.
+
 `current` is a set of version-free links that `jsc-cli:deploy` maintains, so an upgrade moves the cache and leaves these paths alone. When one of them is missing, report the missing link and say `jsc-cli:deploy` has to run; never fall back to a cache path to get the round through, and never create the link here.

 2. **Check the page name.** An empty `hash=` means `jsc-gitea/tools/hash-id` could not be found or could not run, so there is no page to write to and nothing can be recorded. Run `$JSC_HOME/current/jsc-assist/tools/patrol.sh abort --round {round}`, report that the round found its results but has nowhere to put them, name `jsc-gitea` as missing, and stop. Never invent a page name — a hand-made name lands the content on a page nobody reads. Completion condition: `page=` holds a `MONITOR_{HASH}` name, or the abort ran and the round was reported as unrecorded.

    Put the whole page. An old-format page — per-round sections stacked up, no summary table — has no rows to carry over: keep its `本頁基本資料` block, drop the stacked sections, let the table start with this round's row, and say in the report that the page was converted. Only exit 4 from the read permits creating the page instead, and then the body is the whole content of `newpage_file`, which already carries all three blocks. Exit 7 and exit 8 mean the old content is unknown: create nothing, write nothing — rebuilding a page from an unknown original throws the summary table away. On any write failure — including exit 3 with no wiki repo configured for `MONITOR`, which the patrol cannot ask about — run `$JSC_HOME/current/jsc-assist/tools/patrol.sh abort --round {round}`, report the code, and stop. **No record, no heartbeat.** Completion condition: the put or the create returned success and the page holds exactly three blocks with the summary table at 24 rows or fewer and this round's row on top, or the abort ran and the round was reported as unrecorded with its exit code.

This is the last step for a reason: it is the only thing that turns a fresh heartbeat into a true statement.

Close with the 待人處理 rows from the latest-round block, verbatim, and nothing else — the patrol names an entry point and stops there. Completion condition: all four items appear in the report, the heartbeat outcome is stated as written or not written, and no suggestion in 待人處理 was acted on.
