feat(editor): add --gen-zone-mesh-pack orchestrator

Browse source 
Companion to --gen-zone-texture-pack. Drops a 5-mesh starter
pack (3 rock variants + tree + fence) into <zoneDir>/meshes/ by
fanning out to the procedural --gen-mesh-* family. Each rock
variant uses a distinct seed so they read as different boulders.

Together with the texture-pack orchestrator a fresh zone can now
be bootstrapped to first-render-ready state with zero proprietary
M2/BLP imports — entirely from open WOM/PNG output.
