FilePicker

File selection for import/export flows (e.g. picking a receipt, saving an export). Android/iOS: Calf's file-picker/file-saver, bridged from the host's Compose layer — Calf's launchers are @Composable (they wrap rememberLauncherForActivityResult/UIDocumentPickerViewController), so like PermissionsProvider.request's ActivityResult dialog, the actual pick/save UI can't be driven from this headless module and is bridged in by whoever hosts the Compose UI.
