The `wrap` prop changes a <Text> node's MEASURED height (the yoga measure
func reads el.props.wrap to pick wrap/truncate/hard layout) but is NOT a
yoga prop, so a runtime wrap-only change took the generic STYLE_PROPS
branch in patchProp: it stored the new value into el.props and called
onCommit() WITHOUT markTextDirty(el). Yoga kept the OLD wrap mode's cached
height while paint rendered with the NEW wrap, so layout and paint
disagreed -- stale blank rows on wrap->truncate, overflow / overwritten
siblings on truncate->wrap.
Mark the text node dirty when the changed STYLE_PROP is `wrap` on a
tui-text node so yoga re-measures. `wrap` is the only STYLE_PROP that
affects measured dimensions (the rest are paint-only), so it is the sole
case.
Verified Ink v7.0.4 has the identical latent bug -- its applyStyles
ignores textWrap and never markDirty()s, so a wrap-only change goes stale
there too. Recorded as a blessed divergence in ink-divergences.md; the fix
matches the layout Ink produces whenever its measure func is invalidated.
Tests (text-wrap-remeasure.test.tsx) reproduce both directions:
RED produced Ink's stale frame ("aaaa …\n\n\nZZZZ"), GREEN the correct
re-measured layout.
