feat(editor): add --gen-texture-bark tree-bark pattern

Browse source 
Vertical streaks of varying brightness (per-column hash gives
each streak a stable shade in 0.85..1.10) sway-warped per-row
via a slow cosine offset, plus dark vertical cracks at random
columns where bark splits as the trunk expands.

Defaults: density=0.04 (~4% of columns become cracks), seed=1.
Useful for tree-trunk textures, wooden palisades, bark-clad
buildings. Brings the procedural texture pattern set to 24.
