feat(preview): fluted-glass wave generation animation - #73

Conversation
Replaces the img-fx mosaic loader with @paper-design/shaders-react's FlutedGlass in the wave shape — the vertical ribbed treatment the V1 loading frames depicted. The shader is an image filter, so the cut being generated shows through as the project's poster frame with contour distortion, and the ribs sweep gently by animating the texture shift uniform at ~30fps in a leaf component (the Player is unmounted while busy). Fresh projects without a poster fall back to a quiet surface under the label. Dropping img-fx also removes its three.js payload, halving the renderer bundle (2.2MB -> 1.15MB).
