feat(app): add minimal watch app with smoke test and per-size icons

The M0 placeholder app: AppBase entry point, home screen with name and
version, debug-only diagnostics (start-up time, memory) and a unit test
that runs in the headless simulator. Builds with strict type checking
and zero warnings for all 72 products; icons.jungle gives every product
a launcher icon of its exact size.
