feat(lint): flag text-reflow props in gsap_non_transform_motion

Extend the rule beyond positional layout props to the text-reflow props
letterSpacing / wordSpacing / fontSize. Animating them reflows text and snaps
glyph positions to the pixel grid, so a slow ease-out tail micro-stutters
exactly like left/top — measured on a real composition, a slow letterSpacing
"settle" rendered 19/30 unique frames vs 30/30 for the transform-driven
motion in the same piece. They have no transform replacement (fix: settle via
scale or hold the value), and the snap happens during browser layout, upstream
of the canvas raster, so they are never html-in-canvas-exempt. width/height
stay excluded (legit animated uses — progress bars, reveals).

Restructure the finding's message/fixHint to compose per category (positional
-> x/y; reflow -> scale/hold; roundProps -> remove) instead of a two-branch
ternary. Skill guidance (gsap-transforms-and-perf.md) broadened: "layout
property" includes reflow; letterSpacing/fontSize named as the settle-trap.

Migrate the one surfaced positive: registry/components/vignette/demo.html
title settle letterSpacing -> a subtle scale settle (render-verified 20/20
unique frames, smooth). Blast radius across the registry was this one comp,
zero false positives.
