build(mobile): declare App platform compiler to stop build:app false green

`@dcloudio/uni-app-plus` was never declared, so `uni build -p app` silently
fell back to an H5 shell: exit code 0, `DONE Build complete.`, but the output
was only `index.html` (still carrying the `/h5/assets/...` base path) with no
`app-service.js`, `app-renderjs.js` or `manifest.json`. Because
`docs/MOBILE_APP_PACKAGING.md` lists that command as a local verification
step, App platform code was reported as built without ever reaching the App
compiler.

Declare the compiler at the same version as the other `@dcloudio` packages,
guard the version alignment in `tests/app-packaging.test.mjs`, and document
that success is judged by the emitted artifacts, not by the DONE line.
