ToolRowBase

The single-line row most tool cards are built on: a 12px icon, a label that shimmers while isAnimating (shimmerLabel) and settles to completeLabel, a muted truncated detail, and optional trailingContent such as elapsed time. With expandable the row becomes a button with a chevron and reveals children in a Collapse; it works uncontrolled (defaultOpen) or controlled (expanded with onToggleExpand). Other Mantine Box props pass through to the root, so you can add data-* attributes and style props. Use it to build a custom tool renderer that sits in the same visual rhythm as the built-in cards. ContextEventRow, HookActivity, ActionRow and GenericToolRow are built on it. The detail truncates, so the row fits any width.
