Brandon ThomasandClaude Opus 4.8 1c474b8c7e Image > Trap (CMYK prepress trapping)
Clean-room trap: per-ink grayscale dilation (separable max filter,
par_rows/wasm-safe) applied only under already-inked pixels, so internal
colour edges get a trap band while object-vs-paper edges stay clean.
Engine image.trap (CMYK-only, active pixel layer, one history step).
algo 3 tests + engine 2 tests. Parity 607 -> 608; FLOOR 603.
