云服务部-叶林立andDevin <158243242+devin-ai-integration[bot]@users.noreply.github.com> 2682bd7fa7 feat: 组合包配置集中到 my-pi/ 目录并改为整体重建
- 组合包拥有、可随时重建的配置、日志与缓存统一放在
  <agentDir>/my-pi/:permission-system/(policy.jsonc、hard-guards.jsonc、
  logs/)、rtk-optimizer/config.json、tool-search/(config.json、
  catalog-v1.json)与 system-prompt-cover.md。hashline.json、lsp.json
  由外部扩展读取固定路径,是唯一例外。
- 新增 config/bundle-manifest.json 与 scripts/rebuild-bundle-config.mjs:
  先校验全部来源与目标,在临时目录构建完整树,再整体删除旧 my-pi/
  (符号链接只删链接)并原子替换,不备份。install.sh / update.sh 每次
  运行都调用它;扩展自身不再播种或迁移配置。
- update.sh 删除 pi update 失败后的 git clean 恢复逻辑:Pi 1.3.0 会在
  下一次 pi update 时依据中断标记自行恢复。同时删除 Tool Search
  settings.json 快照迁移与封面部署脚本。
- Tool Search 改为读取 my-pi/tool-search/config.json(源为
  config/tool-search.json,须与 BUNDLE_TOOL_SEARCH_DEFAULTS 一致),
  不再读写 settings.json 的 toolSearch 段,移除 bundleDefaultsVersion。
- 默认权限策略开启 debugLog。
- 旧位置的残留文件不迁移、不清理;AGENTS.md / README 同步新约束。
