Adds stream API

[natemoo-re]

This PR adds a stream API which has all the same methods as log but has support for Iterator and AsyncIterator. This is particularly useful for AI responses which are dynamically generated by LLMs.

stream.info((function *() {
  yield 'Info!';
  yield* generateLLMResponse(question);
})());
stream.success((function *() {
  yield 'Success!';
  yield* generateLLMResponse(question);
})());
stream.step((function *() {
  yield 'Step!';
  yield* generateLLMResponse(question);
})());
stream.warn((function *() {
  yield 'Warn!';
  yield* generateLLMResponse(question);
})());
stream.error((function *() {
  yield 'Error!';
  yield* generateLLMResponse(question);
})());

Huge thanks to @mattpocock for the original feature request on Bluesky.
