AndroidFilePicker

class AndroidFilePicker(context: Context) : FilePicker

Android FilePicker. Calf's rememberFilePickerLauncher/rememberFileSaverLauncher are @Composable (they wrap rememberLauncherForActivityResult), so — mirroring AndroidPermissionsProvider.requestBridge — the host activity's Compose layer registers pickBridge/saveBridge to the real launchers; with no bridge registered this degrades to reporting no file rather than crashing. File bytes are read via Calf's KmpFile I/O, which is plain suspend code, not Compose-bound.

Constructors
