feat(editor): add --gen-mesh-weathervane rooftop primitive

Browse source 
53rd procedural mesh: 6-box rooftop wind indicator — base
plate, tall vertical post, perpendicular N-S and E-W cross
arms (cardinal direction markers), a long horizontal arrow
on top of the cross, and a small tail box at the back end of
the arrow that visually balances the head and gives the arrow
its directional read.

Useful for farm rooftops, chapel spires, town halls,
lighthouse caps, manor turrets — anywhere a fantasy world
wants visible wind direction. Defaults to a 1.50m post with
0.40m cross arms and a 0.55m-half-length arrow (~1.67m total).
