Brandon ThomasandClaude Opus 5.5 48d1a4f9e5 Never crash: cms is panic-free (Rule 9) (#36) ...

- Real crash: a gray ICC profile whose A2B0 tag is stored as "mBA "
  parsed fine, but re-encoding its RGB view (gray_as_rgb, used for gray
  documents' composites) hit panic!("unsupported lutAtoB stage layout").
  The ICC writer now leaves out a LUT its tag type can't store, and
  gray_as_rgb drops the gray LUTs (one input channel) so the RGB view is
  the matrix/TRC model it builds. Regression test
  gray_profile_with_reversed_lut_type_reencodes.
- math::rgb_to_xyz_matrix returns None for dependent primaries.
- Builtin::profile indexes its cache by discriminant (tested); the shipped
  CMYK profile falls back to synth::coated_cmyk() instead of expect.
- Two constant-only expects (Bradford inverse, built-in primaries) use the
  documented narrow allow.
- cms denies unwrap/expect/panic/unimplemented/todo/unreachable.
