Streaming

Agent#stream returns a replayable StreamResult:

stream = agent.stream(input: "Research this topic", client: client)

stream.text_stream.each { |delta| print delta }
completed = stream.result

Use reasoning_stream, item_stream, or full_stream for other projections. Ruby consumes provider streaming synchronously and then exposes replayable sequences to additional consumers. Item values are currently hashes rather than the TypeScript discriminated item union.
