feat(editor): add --gen-mesh-candle wax-pillar primitive

Browse source 
80th procedural mesh primitive. Wax pillar candle:

  • saucer (optional) — wider shallow disc base, the drip
    catcher that sits on the table
  • wax — thin tall pillar standing on the saucer (or
    directly on the ground if saucerR=0)

Uses the addClosedCylinderY helper for both pieces — same
two-cylinder pattern as --gen-mesh-bird-bath but with a
much skinnier upper cylinder. The 81-line handler is
mostly arg parsing + validation; geometry is just two
helper calls.

Useful for chapels / shrines, vigil scenes, witch-hut
ritual surfaces, alchemist labs, séance tables, festival-
of-lights ground decoration. Set saucerR=0 for a plain
candle without the saucer (e.g. for stack-them-on-a-cake
contexts).

Watertight under weld (verified — wax + saucer are two
independent closed cylinders).

Milestone: now at 80 procedural mesh primitives.
