重构: df-miniapp移入apps/(monorepo分层 crates=Rust库/apps=前端应用)

- df-miniapp/ -> apps/df-miniapp/(uni-app 工程归集前端应用层,与 crates/ Rust 库分层)
- 删冗余 apps/df-miniapp/.gitignore(根已覆盖 node_modules/dist/.DS_Store 等)
- 根 .gitignore 加 unpackage/(uni-app 编译产物,唯一根未覆盖项)
- vue-tsc 零错(移动不改代码,类型不变)

apps/df-miniapp/manifest.json
