Brandon ThomasandClaude Opus 5.5 c812352940 M5: highlight reconstruction starts at half resolution (2-2.5x faster, identical output) ...

A clipped pixel is never valid at full resolution, so its diffused chromaticity was always the
bilinear sample of the half-resolution pyramid level; the full-resolution chroma field (288 MB
at 24 MP) and its fill pass were wasted work. The pyramid now starts at half resolution straight
from the image. Bit-identical to the previous implementation (kept as a test reference over odd
sizes and clipping densities). 24 MP: 319 -> 145 ms isolated; real CR2/ARW loads 0.8-1.1 s ->
0.3-0.5 s under load. Runs on every full-resolution raw load (1:1 loupe, export).
