feat(editor): add --gen-mesh-grave tombstone primitive

Browse source 
Two-box composite: a wider low base + a vertical tablet
centered on top. Base is deeper than tablet (1.5×) and base
height is 20% of tablet height — proportions that read as a
stable foundation supporting an upright stone.

Defaults: tablet 0.6×1.0×0.15, base width 0.8. Useful for
graveyards, undead zones, memorial set dressing, ruined
chapel courtyards. Brings the procedural mesh primitive set
to 32.
