#
DeviceId

type DeviceId = UInt

This is intentionally a small, testable slice: device enumeration and names.

Map CoreAudio OSStatus into a cross-platform SupportedStreamConfigsError.

This mirrors CPAL's intent: classify only the small set of errors that have stable meaning across backends, and fall back to a backend-specific error for the rest.
