feat(editor): add --gen-mesh-table furniture primitive

40th procedural mesh: simple 5-box table — flat top slab on
4 vertical corner legs. Pairs with --gen-mesh-bench /
--gen-mesh-throne / --gen-mesh-bookshelf for taverns,
dining halls, libraries, and study set dressing.

Defaults to 1.6 × 1.0 base × 0.85 tall, 0.10-square legs,
0.06-thick top — sensible dining-table proportions.
Customizable per dimension so a single primitive covers
desks, end tables, and big banquet tables.
