Updates on Streaming Tool Output?

Hi, is there any progress on streaming tool output while a tool is still running?

Right now it looks like the SDK gives me "tool started" and then the final content/result when the tool is done. What I am looking for is the stdout/stderr lines while the command is running.

Example: if a tool runs something like `npx create ...`, `npm install`, a build, or a dev server startup, the command prints useful lines while it runs. In the SDK those lines seem to be hidden until the tool finishes.

I found these related issues:

- #343
- #213

So maybe this is already tracked, but I wanted to ask:

- Is this currently possible with the SDK?
- If not, is it planned?
- Is there a recommended workaround for now?

Main use case: showing real command output in a UI instead of a spinner until the final `tool_result`.
