#185152 adds a Hyphens API (ParagraphStyle.hyphens, Text.hyphens, etc.) so that soft hyphens (U+00AD) render as a visible hyphen at line breaks. On native platforms the engine passes this through to Skia's ParagraphStyle::setRenderSoftHyphens.

CanvasKit and Skwasm now render soft hyphens: CanvasKit in #194339 (with Skia's binding from https://skia-review.googlesource.com/c/skia/+/1378836) and Skwasm in #193850. WebParagraph, the experimental pure-Dart text renderer, still stores hyphens without acting on it: its line breaker and painter don't draw a hyphen when a line breaks at U+00AD.

Splitting this out of #18443 so that #185152 can close that issue for native platforms, per #185152 (comment).

Related: #189617 (customizing the hyphen string), #189234 (hyphen glyph excluded from selection highlight).
