Brandon ThomasandClaude Opus 5.5 681a57fc1a Rendering: kerning and automatic paragraph spacing like Word (#923) ...

Found by rendering 12 US government Word documents (NIH, EPA, MCC) in
Word for Windows and WordCraft and comparing the pages side by side,
then pinning each rule down with synthetic documents measured in Word.

- Kerning: the shaper kerned every run, so WordCraft's lines held more
  text than Word's and broke differently. Word kerns only a run with
  Kerning for fonts (w:kern) at or above that size; no w:kern and
  w:kern="0" are unkerned. New documents keep kerning from 1 pt, like
  Word's Normal template.
- Automatic paragraph spacing (w:beforeAutospacing/w:afterAutospacing,
  common in text pasted from web pages) was ignored. It is 14 pt at
  any size, none before the document's or a cell's first paragraph,
  none after a cell's last, and the larger of two neighbouring spaces
  counts. Read, written back, and settable through para.spacing
  (beforeAuto/afterAuto); a number, Ctrl+0 and Remove Space After
  replace it as in Word.
