Kelsi 4df8661017 feat(editor): add --gen-texture-rust oxidized-metal pattern ...

3-octave smooth noise field thresholded by `coverage` to make
rust blob regions, blended with the metal base color via a
0.12-wide smoothstep so patches feather into clean metal
rather than stepping. Per-pixel grain jitter on top so neither
material reads as flat.

Defaults: coverage=0.4 (~40% rust), seed=1. Useful for
weathered armor, abandoned machinery, ruined castle gates,
shipwreck debris. Brings the procedural texture pattern
set to 29.
