Brandon ThomasandClaude Opus 5.5 a0da99660d M4.2: optics — manual distortion/vignetting, lateral CA (auto + manual), defringe, DNG-embedded profile corrections ...

- pipeline::optics::Warp: one inverse map (lens-corrected → source) inside the single geometry resample:
  manual radial distortion, embedded DNG WarpRectilinear (per plane), per-channel lateral CA scale,
  radial vignetting gain (manual + embedded FixVignetteRadial); all in normalized radii
- automatic lateral CA estimate: radial edge profiles matched sub-pixel per plane, robust LSQ fit of
  displacement = α·r (cached per source)
- defringe: purple/green hue ranges (OkLab hue) desaturated next to high-contrast edges, width relative
  to the image long edge
- "Enable Lens Corrections" applies only lens data embedded in DNGs (opcodes are no longer baked at decode;
  stored on the photo record, on by default at import when present). No LCP data anywhere.
- new controls: optics.caRed/caBlue, defringe hue ranges; Optics panel: Manual sub-section, Defringe flyout
- tests: barrel grid straightened, CA removal (auto + manual), embedded corrections toggle/scale, preview vs
  export resolution independence, CA estimator accuracy, orientation of embedded lens data
