FEAT: SelectorGroupChat could using stream inner select_prompt (#6286)
## Why are these changes needed?

This PR updates `SelectorGroupChat` to support streaming mode for
`select_speaker`.
It introduces a `streaming` argument — when set to `True`,
`select_speaker` will use `create_streaming()` instead of `create()`.

## Additional context

Some models (e.g., QwQ) only work properly in streaming mode.  
To support them, the prompt selection step in `SelectorGroupChat` must
also run with `streaming=True`.

Closes #6145
