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.
