Release v0.0.02-pre: car dashboard, nav bar rework, cached launcher

- Nav bar is icon-only and shorter, with a now-playing pill on non-home screens
- Clock opens a calendar and weather dashboard (adds READ_CALENDAR)
- Web page URL is now set from the car's Settings screen
- Launcher app scan and weather are cached
- Home player gains skip buttons and a larger cover
