Cobblemon Survival Pack: phases 0-2 and Phase 3 zones and hazards

Free NeoForge 1.21.1 modpack on Cobblemon 1.8.4 built with packwiz, plus
the Kotlin companion mod (cobblesurvival) and its built-in data pack.

- Phase 0: packwiz pack with Modrinth/CurseForge cross-links, build and
  export tooling, Prism instance sync, test server with smoke checks.
- Phase 1: Poke Ball shaped island (WorldGen Editor preset, seed isle-26),
  Adrian's biome list, no natural ore, structures without ore or vanilla
  mobs, no Nether portals, world template builder and world report.
- Phase 2: permadeath (CobbleHardcoreMon plus the companion mod's gap
  fixes), Revival Charm, expensive Healing Machine, Lootr refreshing
  loot, in-game self-tests on Minecraft's GameTest framework.
- Phase 3 so far: 14 zones with their own spawn pools and level bands
  (tools/zone_layout.py, tools/zone_spawns.py, "zone" spawn condition),
  Cold Sweat heat and cold as gates with boss-drop insulation recipes,
  spawn survey and hazard self-tests in tools/quick_check.py.
