feat(editor): add --gen-mesh-gate wooden farm-gate primitive

Browse source 
51st procedural mesh: 5-box wooden gate — 2 vertical posts on
either side and 3 horizontal cross rails (top, middle, bottom)
spanning the opening. The gate sits flat in the X-Y plane
(rails along X, posts along Y) so it can hang in a wall slot
or fence gap without needing rotation.

Useful for fenced fields, manor entrances, pen openings,
courtyard barriers, dungeon archway closures. Defaults to a
1.80m opening with 1.30m-tall posts. Pairs with
--gen-mesh-fence for complete enclosures, exporting through
the open-format ecosystem (WOM -> OBJ / GLB / STL) so designers
can preview the gate-to-fence joinery in any external tool.
