"""Quick Edit support for Photoshop's Type ▸ Warp ("warp the text").

The editor already had a full retained-text warp pipeline (static/js/editor/
text-layer.js `warpCanvas`, and `warp`/`warpAmount` on the text data), but the
Quick Edit client fast path never routed a warp request, so "warp the text"
fell through to "No built-in quick action matched". These tests pin the new
deterministic branch in galleryEditor.js `_executeQuickEditLocal`.
