Phase 3: the Mangrove Mire poisons anyone without Mire Waders

- Companion mod zone hazards (zone/ZoneHazards.kt, data in
  data/cobblesurvival/zone_hazards/): in the Mire a player without an
  item from #cobblesurvival:mire_protection gets Poison every 5 seconds,
  with a one-time warning. Potions, milk and golden apples still help.
- Mire Waders: KubeJS leather boots, dropped by the Westmarch and Verdant
  Jungle guardians (the zones before the Mire), per Adrian's boss rule.
- Self-test mire_poisons_without_waders.
- Allow-list Cobblemon's misspelt jigsaw state in
  habitats/parched_peat_bog7.nbt, which test players now reach.

 - Basalt Furnace got Durant, Torkoal and Heatmor pinned to it: its own lines were all big (Charizard, Turtonator, Centiskorch, …) and Cobblemon only spawns a Pokémon where its body fits, so cramped basalt caves stayed empty.
 - Tested: `spawn_pools_are_zoned` (no Cobblemon default spawn is left; every entry has a zone and spawns within its band) and `spawn_survey` (a player at a point deep inside each zone is offered only that zone's spawns, and at least one), both in `tools/quick_check.py`.

Mire Waders (leather boots, a KubeJS item) drop from the guardians of Westmarch and the Verdant Jungle, the zones before the Mire. Tested: `mire_poisons_without_waders`.

 - The guardian is the strongest Pokémon that spawns walking (or, at sea, swimming) in its zone, five levels above the band, half again as big, and uncatchable: Pachirisu (Button Isle), Sigilyph (Southwold), Carbink (Westmarch), Tangrowth (Jungle), Arcanine (Mire), Cinderace (Highlands), Delphox (Sunscorch), Tyranitar (Frostpeak), Kingdra (Deep Sea), Dusknoir (Deep Dark). `world/zones.json` → `guardian.species` overrides the pick.
