Native Android still capture belongs to the application's Camera2
implementation in 3.0.4. Flutter provides higher-level capture through its
native platform view.

## Important ownership rules

Request camera permission before opening Camera2. Stop any previous controller
before starting Nosmai. Camera device error `2` normally indicates that another
session still owns the camera.
