World: flora feel fix — kill double-animation (root sway off, shader wind is the idle motion) + thin flowers

Operator: base flora too dense + "the waving/shader doesn't look great". Diagnosis: EVERY Synty flora prop (both biomes) uses the Synty/Foliage VERTEX-wind shader — the transform root-tilt sway has been double-animating all flora since 1.5, and ground-flush carpet props (Flowers_Flat, Grass_*_Plane) visibly lift their edges when tilted. - AmbientMotionConfig.SwayEnabled -> false (code default + the serialized scene value): idle motion = the authored per-vertex shader wind (tips bend, bases planted). Knob kept for A/B; walk-through RUSTLE stays as the reactive layer the shader can't provide. - AmbientMotionSystem: flat carpet props excluded from the flora cache entirely — no tilt even from rustle. - Flower density thinned deterministically: Flowers_Flat keep 40%, Wildflowers/Sunflowers keep 50%, center (r<13) thinned harder (x0.6) — 17/38 drifts off; play/build area reads clear, flowers become ring accents. Console clean; sway/rustle knobs remain live-tunable in the scene. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
