TwilightService v2.0
- Switched to using CalendarAstronomer for more accurate sunrise/sunset
times.
- Exposed sunrise/sunset times via TwilightState so that clients can
track the current twilight period and perform their own
interpolations.
- Adopted LocationRequest API for fused location updates:
(low power, min 1h, max 10m).
- TwilightService is now only activated when a listener is registered,
minimizing impact to system health on platforms / configurations
where twilight state is not needed.
