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

Browse source 
New zone-scope command that drops a 6-texture starter pack
(grass, dirt, stone, brick, wood, water) into <zoneDir>/textures/
by fanning out to the procedural --gen-texture-* family. Saves
users from sourcing proprietary art when bringing up a new zone —
the entire pack is open PNG output from procedural generators.

Adds to the gen-random-zone family of project orchestrators.
