0.24.0 — Grouped editor token lists; CodeSnippet horizontal scroll

Added

• CodeSnippet scrolls long lines horizontally. Long code no longer truncates
  with an ellipsis; it scrolls on the x-axis behind a thin styled scrollbar, and
  the copy button stays pinned to the top-right. Two new tokens style the
  scrollbar, both editable in the CodeSnippet panel:
  --codesnippet-scrollbar-thumb (thumb color) and
  --codesnippet-scrollbar-border-width (scrollbar thickness).

Changed

• Editor token lists are now split into labeled element groups. Ten
  component editors (Callout, CodeSnippet, InlineEditActions, Input, MenuSelect,
  ProgressBar, SegmentedControl, TabBar, Toggle, Tooltip) group their tokens
  into labeled sections (frame / text / icon and structural parts like track,
  thumb, divider, indicator, scrollbar) via the element field instead of one
  flat list per state. Editor-only change: rendered output for existing tokens,
  token names, and component APIs are unchanged, so existing themes and
  component-configs are unaffected.
