chore: .gitignore 遮蔽历史会话遗留的一次性脚本与临时输出

424 个未跟踪文件（多会话积累的 explore/test/verify/deploy/debug/probe
一次性脚本 + 截图/文本 dump）→ 剩余 26 个（Docs、其他功能 HANDOFF、
在开发的文档管理模块）。

- 根目录 + backend/ 根目录 + backend/scripts/ 按前缀遮蔽一次性脚本
- 遮蔽 *.txt/*.json/*.png/*.jpg/*.html 调试 dump 与 exec_shots/ 等目录
- 仅影响未跟踪文件；已跟踪文件（main.py/config.py/package.json/
  app/data/*.json 等）不受 ignore 影响；如需纳入版本控制用 git add -f
