Collapsed command rows rendered "Command" plus the raw result JSON as
the preview; the command itself is the useful collapsed line, so it now
renders as the row text (whitespace-collapsed, truncated) with stdout
and the full payload behind the expander. Tool-like headings drop the
bold foreground for the muted secondary-label the summary rows use, and
the "+N previous tool calls" toggle loses its bold black label for the
same muted treatment.
