WIP: ore nodes, catching rules, bee nest fix, smaller Deep Dark

Done and checked: surface and cave-floor ore nodes (companion mod
ore/OreNodes.kt), bigger and rarer underground veins; template with nodes
passed the world check and the island quick check (node self-tests).

Built, not yet tested: catching rules (catch rate falls with the level
gap to the trainer's strongest Pokemon, failed catch enrages, strong wild
Pokemon hunt weaker trainers; catching/, Fight or Flight config), bee
nests emptied when their bee is turned away.

In progress: the Deep Dark no longer fills the deepslate layer (split by
temperature: cold = Deep Dark, hot = basalt deltas, warm = ordinary caves;
world/biomes.json), zone layout regenerated; cave zone types added to
world/zones.json but tools/zone_spawns.py doesn't use them yet; template
not rebuilt for the new caves.

-Builds the island world template (`build/world-template`, about 20 minutes: pregeneration, then a pass that waits until every chunk has its ore veins, then the showcase veins), runs the same world checks on the whole island plus border fit and End access, and renders `build/island-map.png`.
