v0.33.1

Fixed

• Author's Voice pending-diff highlight on partial selections. When an Author's Voice rewrite replaced a mid-paragraph (sub-paragraph) selection, the blue/green pending decoration highlighted the wrong character range (a mid-word cutoff, or only the unchanged prefix) because it trusted selection offsets that a holistic rewrite invalidates. The highlight is now computed from a real text diff (longest common prefix + suffix) of the original vs rewritten node, so it covers the actual changed span. Whole-node and multi-node selections are unchanged, and accepted text was always correct — this was cosmetic only.
