Prevent rich inline boundary overflow

Fixes #120. Refs #132.

Wrap before a new rich inline item when the lower line walker only made forced progress that would overflow the current partially-filled line. This keeps split CJK inline fragments, and the same boundary shape in other scripts, inside the requested width.

Refresh benchmark snapshots and status dashboard.
