perf(artwork): compute the blurhash DCT separably (#5989)
The cosine basis factors into cosX[i][x] * cosY[j][y], so the pixel loop
does not need to visit every (i,j) pair. Each row now collapses to xComp
dot products, folded over yComp once per row: w*h*xComp + h*xComp*yComp
multiply-accumulates instead of w*h*xComp*yComp.

Encoding is ~60% faster at every input size, and ~80% faster at the 128px
size the artwork pipeline actually feeds it (263us -> 53us). Hashes are
byte-identical, so the existing golden-value specs cover the rewrite.
