LR-PROF-IMPORT: .cube 3D LUTs as creative profiles

Browse Source 
lightcraft-pipeline gains lut.rs: a .cube parser (LUT_3D_SIZE, DOMAIN_MIN/MAX, TITLE), a
trilinear lookup and an in-process registry; the finishing stage applies a `lut:` profile to
the display-encoded colour, blended by the profile amount (0–200 %); LUT profiles render on the
CPU. profile.import {paths} reads files, folders and zips, copies each LUT into the library's
Profiles/ folder, lists them in prefs and registers them when the library opens; the profile
browser shows them under their folder / zip name; profile.deleteImported. File ▸ Import
Profiles & Presets…, the file picker and drag & drop take .cube files.
