Durable text batches

Added

Before: Text batch operations did not exist
After: Text batches can be started and queried

Applications can submit multiple text-generation requests as one durable batch, check its lifecycle status, and stream completed item results. Only models declaring batch support are accepted.

In favour

In favour: Rejects empty or duplicate request IDs before provider calls
In favour: Cancelling result streams aborts the provider operation

Against

Against: Core and batch code now import each other, three edges total
