Interface HostServicesOptions

Makes room for a checkpoint about to load; see WhisperModelHostOptions.admit.

Test seams.

The host's event bus, shared with whatever else publishes (the engine adapter); default a new one.

The host's exclusive lock around decoding; without one decoding runs at once.

Downloads and publishing behind the default catalog; a host without them cannot fetch or push models.

Lifecycle lines of the model host ([transcription] X loaded in 60 ms); default the console, which a verb printing to stdout must silence.

Where declared storage entries live; default MLX_BUN_HOME.
