feat: 组合包配置以包内 config/ 为唯一来源，并新增受保护写入人工审批

配置统一：权限策略、硬防御、Tool Search、提示词封面以及新迁入的
RTK、pi-compaction、pi-worktree、pi-hermes-memory 配置全部由扩展
直接读取已安装组合包内的 config/，pi install / pi update 即完成部署；
删除 rebuild-bundle-config.mjs 与 bundle-manifest.json，my-pi/ 只保留
日志与缓存。update.sh 成功升级后将默认 git 来源的已安装副本
reset 回发布版本。AGENTS.md 新增「组合包配置原则」。

脚本整合：search_config.sh / ssh_config.sh 合并为 configure.sh
search|ssh；install.sh / update.sh 共享函数抽到 scripts/lib.sh，远程
安装器改为先下载到临时文件再执行，下载失败可被检测。

权限：hard-guards 新增 protectedWrites，写入 Pi 凭据/设置、已安装
组合包与扩展目录、pi-ssh 凭据库时一律人工确认（跳过 AutoReview、
yolo 与 Session grant，无 UI 时拒绝）；放行 ls、LSP 查询、ctx 只读、
web_search、Chrome 只读与 git 只读命令，skill_manage 改为 ask。
