docs(readme): expand Setup & Building quick start for all platforms

Restructure the quick start with Web, Android, and iOS subheadings; put
each npm command in its own code block; fold the test-page step into the
Web section. Document Android (build:android:test:run + ADB, link to
BUILDING.md) and iOS (build:ios:studio + Xcode prerequisites).
