refactor: 清理 registry 条目 — 移除运行时字段，规范静态数据

Apps（8 个）:
- 删除顶层 requirements（已在 install.requirements 中）
- 删除 installStatus、latestVersion（运行时/冗余字段）
- 将 configNeeded 移入 install.configNeeded
- 删除 install 内的 composePath/envTemplatePath

MCP（7 个）:
- 删除 protocol/status/origin/transport（由 sync 层按目录类型注入）

Services（5 个）:
- 删除 protocol/status/origin（由 sync 层注入）

原则：Registry 只存静态数据，运行时字段由客户端 sync 层注入默认值。
