feat(editor): add --gen-mesh-scroll-case library prop

Browse source 
84th procedural mesh primitive. Cylindrical scroll case /
map tube:

  • body — thin tall Y-axis cylinder (the case proper)
  • cap (optional) — shorter wider cylinder on top, set
    capR=0 to skip for a bare stick / rolled-document spine

Distinct from --gen-mesh-chalice (foot + stem + bowl
silhouette) and --gen-mesh-lantern (4-tier base + globe +
neck + cap) — scroll case is the simplest 1-or-2-tier
"tube with lid" prop.

Useful for wizard-tower libraries, archive shelves, mage-
hut detail trim, scribe-table props, scout-courier waist
gear. Validates that capR >= bodyR so the lid always reads
as a proper top closure rather than a degenerate band.

Watertight under weld (verified 168 manifold edges, 0
boundary, 0 non-manifold). Two more clean uses of the
addClosedCylinderY helper.
