Subject: [PATCH] fix: expand tool calls by default when Response Style is
 Detailed

When responseStyle is set to 'detailed', the ToolCallExpandable
wrapper and ToolResultView should both start expanded. Previously,
isStartExpanded for the wrapper was only set when rendering live
progress, and ToolResultView always started collapsed regardless
of the response style setting. Fixes #8213.
