feat(log): 工作日誌支援待寫入暫存

What：新增 tools/worklog-pending.sh，worklog 技能改成寫入前先併入暫存內容、寫成功後才清除。

Why：SDLC 階段跑完沒寫工作日誌時，內容如果只留在對話裡，換一個工作階段就補不回來了。

How：暫存放在 $JSC_HOME/worklog-pending/{HASH}/，檔名帶 UTC 時間與 pid，同一秒的兩個工作階段不會互相覆蓋。jsc-sdlc 的階段回報負責存入，worklog 負責併入與清除；清除排在 wiki 寫入成功之後，先清再寫會兩邊都沒有。

Who：用 jsc-sdlc 跑階段、事後要靠工作日誌回頭查的人。

+# worklog-pending.sh — 待寫入工作日誌的暫存區（供 jsc-sdlc 階段回報與 jsc-log:worklog 使用）。
+#
+# 為什麼要有這支腳本：SDLC 每個階段結束都要回報工作日誌連結。階段跑完卻沒寫日誌時，
+# 內容如果只留在對話裡，換一個工作階段就消失了，下次寫日誌也補不回來。所以暫存搬到檔案層：
+# 階段回報發現沒有日誌，就把該階段的內容存進本區並警告使用者；下次 jsc-log:worklog 寫入時
+# 先把本區的內容一併寫進去，寫完才清掉。
+#
+# 用法:
+#   worklog-pending.sh add <hash> <file>   把一段待寫入的日誌內容存起來，印出存放路徑
+#   worklog-pending.sh list <hash>         列出該 hash 的暫存檔路徑（一行一個，依時間排序）
+#   worklog-pending.sh cat <hash>          依時間順序印出全部暫存內容
+#   worklog-pending.sh clear <hash>        清掉該 hash 的暫存（寫入日誌成功後才做）
+#
+# <hash> 為 jsc-gitea/tools/hash-id 算出的 8 碼工作日誌 hash，也就是 LOG_{HASH} 的 HASH。
+# 存放位置: $JSC_HOME/worklog-pending/{hash}/{UTC 時間}-{pid}.md（JSC_HOME 預設 ~/.jsc）
+#
+# 結束碼: 0=成功 1=讀寫失敗 2=用法錯誤 3=該 hash 沒有暫存內容
+#
+# 陷阱:
+#   - clear 只在日誌確實寫進 wiki 之後才呼叫。先清再寫，寫失敗就兩邊都沒有。
+#   - 檔名帶 UTC 時間與 pid，同一秒內兩個工作階段各存各的，不會互相覆蓋。
