Skyler Lehmkuhl 318720f89d Fix gamma handling and improve brush canvas performance 
Color correctness:
- Unpremultiply before the sRGB OETF on the display and export blits;
  encoding premultiplied color corrupted antialiased/transparent edges.
- Tag exported video as full-range BT.709 (matrix/primaries/transfer).
- Run perception effects (invert, brightness/contrast, hue/saturation)
  in gamma space to match standard editors.
- Interpolate gradients in gamma space across the raster and vector paths.
- Render effect thumbnails in the same linear space as the live pipeline.

Brush performance:
- Store the raster canvas as Rgba16Float (no shadow banding from 8-bit
  linear), with an incremental per-tile ping-pong sync replacing the
  per-frame full-canvas copy.
- Do the linear->sRGB readback conversion on the GPU and reuse a cached
  scratch texture, dropping a ~110ms-per-stroke CPU decode.

Cleanup:
- Single COLOR_WGSL prelude and shared CPU sRGB scalars instead of ~8
  duplicated copies of the transfer functions.
- Shared compute-pipeline builder; smudge folded onto the tile-sync path.
