v0.80.0

Writer

• Relationship-free w:tcPrChange priors that include w:textDirection (lrTb / bRl / �tLr / lrTbV / bRlV / bLrV) are now reviewable as cell-formatting with accept/reject, live track-changes, and native DOCX export (including current-cell write).
• Broader cell property sets remain opaque or fail-closed; opaque fixtures now use cFitText instead of extDirection.
