Default bash tool output to expanded in chat

[markijbema]

Summary

• Changes the default state of the bash/shell tool output block in the chat UI to be expanded (not folded) by default
• Previously it defaulted to collapsed; now it defaults to open so terminal execution output is immediately visible
• Callers can still pass defaultOpen={false} explicitly to override the new default

The change is a one-liner in packages/ui/src/components/message-part.tsx: defaultOpen={props.defaultOpen ?? true} in the bash tool's BasicTool render.

WARNING: Hardcoded defaultOpen overrides tool-level default behavior

Setting defaultOpen unconditionally here overrides any props.defaultOpen value passed from the message part pipeline. This can silently bypass existing shell expansion preferences/flags and force all bash tool outputs open, which risks UI noise and unnecessary rendering cost for large command outputs. Consider deriving this from props.defaultOpen (or a dedicated feature flag) instead of hardcoding it.
