feat(editor): add --gen-texture-flame fire pattern

Browse source 
Vertical color gradient from dark (bottom) to hot (top), mixed
with multi-octave smooth noise so the flame boundary wavers
randomly rather than reading as a clean horizontal line.
Vertical position curve is squared so the dark stays dark
longer and the hot saturates faster — matches real-flame
appearance where most of the body is dark with a bright tip.

Useful for torches, braziers, magical effects, lava-zone set
dressing, fireplace texture details. Brings the procedural
texture pattern set to 32.
