This adds support for sync streams by porting the API from Kotlin:
syncStream()on a PowerSync database instance returns a handle that can besubscribe()d, returning aSyncStreamSubscription.SyncStreamSubscriptioncan be used to wait for that subscription to first sync.SyncStatusData.forStreamto get the current status for a stream.All of this is implemented by delegating calls to the Kotlin equivalent. This also means that it's quite light on tests (reliably testing this would require porting the approach of mocking streaming HTTP responses, but the functionality is covered by Kotlin tests.
I've also added sync streams to the demo as an opt-in. Marking them as enabled via secrets would make the demo load list items on-demand as the user navigates to them.
