dev-null-undefinedandClaude 8c64c467f5 LR-EDIT-OPTICS-PROFILE: Sony lateral CA planes off by default (the demosaic already hides most of it) ...

Verified on 54 ILCE-7RM6 photos, the CA planes made the render worse: our
demosaic already hides about 70 % of the lens CA (the render shows 0.29x
the raw-CFA CA) while the post-demosaic warp moves R and B by 0.84x the
table, so the corner R/G and B/G CA went from rms 0.032 / max 0.125 px
(off) to 0.052 / 0.219 px (on) at 1440 px; only the 16-35 mm improved.

warp_opcode takes a lateral_ca flag; lens_opcodes passes false, so a Sony
ARW gets the one-plane distortion warp. The CA conversion stays live and
tested (FF and APS-C examples, both lossless corpus files' tables). The
follow-up is to warp the CFA colour planes before demosaic. The doc,
tracker (docs/parity-checklist.md), docs/gaps.md, docs/raw-parity.md and
whats-new say distortion applied, CA parsed and off
by default, vignetting not applied; the one-plane default costs 24 -> 45 ms
in the sample stage at 1920 px (three planes: 112 ms).
