dispatcher

The dispatcher on which events are stamped and persisted when the transport does not stamp in its own pipeline (e.g. the iOS Segment bridge, or a custom transport). It must be single-threaded / serial so sequence numbers keep their call order; the default is a single-slot view over Dispatchers.Default that owns no thread of its own. Override to integrate with your own threading, or set Dispatchers.Unconfined in tests to stamp synchronously.
