fix(words): slash menu wider + description wraps to 2 lines instead of ellipsis (F4.5a)

Before:
- Menu width was 7× button-size (≈224px), so even short descriptions
  clipped: "Large section headin…", "Blockquote callou…".
- Description was single-line nowrap+ellipsis, doubling the clipping.

After:
- Menu width 10× button-size (≈320px) — enough room for the longest
  default description ("Large section heading") without truncation.
- Description switches to a 2-line line-clamp with line-height 1.3,
  so longer custom descriptions still degrade gracefully instead of
  silently disappearing past the first line.

Label still nowrap+ellipsis (the bold first line is supposed to be a
short title; if it doesn't fit, that's an author issue worth a visual
cue).

CSS-only in words.css. Visible immediately on the demo's SlashMenu.
