init: workbuddy_skills 重建，仅收录 session-mechanism

- 按用户指示清空原有 25 技能内容，只提交 session-mechanism（57 文件）
- 附 .gitignore（产物 + 本机凭据）
- 令牌明文已脱敏（历史 .neodata_token 与 pitfalls 引用均不入库）
- 本提交为孤儿提交（父提交为空），历史自此重新开始

+"""handoff-status.py — 一条命令看清 05-交接单 里哪些单子【待执行】/【已完成】/【无状态】。
+
+为什么需要它：`05-交接单/交接单-已完成/` 那层目录摊平后，**"目录位置"不再表达状态**。
+状态改由**机读字段**承载（与布局解耦，摊平/搬家都不失效）：
+  ① 单子头部 `- 状态：…` 行（模板已有）→ ② 回退取 `05-交接单/README.md` 台账表的「状态」列
+
+用法：python 07-scripts/handoff-status.py
