kernel: dither gradient shader to kill 8-bit banding (TPDF ~1 LSB)
The shader-based gradient (linear/radial) fragment shader now adds a
mean-zero triangular-PDF dither (~1 LSB of 8-bit) from a spatial pixel-position
hash before writing finalColor, so smooth ramps (e.g. an alpha fade) no longer
show quantization banding when written to the 8-bit surface buffer. Spatial,
non-temporal — no shimmer on static panels. Applies to every shader gradient.
