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.

 **Adrian's answers (2026-10-30):** Cobblebase's skills look fun and stay in, gated behind progression; power comes from an existing mod, also gated (Cobblemon Poke Power); evolution stones as ores are fine for now; the balance values are fine for now and stay configurable, to tweak later.

Each ore tier lives in exactly one zone, higher tiers in higher zones (table in `docs/balance.md`). Adrian (2026-10-30): ore shows up mainly as **small nodes on the surface**, the **larger veins underground are harder to find**, and the cave zones' ores are **nodes on the cave floor, not in the walls**. `tools/zone_ores.py` writes the vein mod's config (`pack/config/regenerating_ore_veins/`) and the node table from `world/zones.json` → `ores`:
- A surface zone is a set of boxes cut from the zone grid; the mod checks every block of a vein against them, so no vein block lies outside its zone. Cave biomes are zones of their own, so surface tiers stay out of them; the mod checks the biome only at a vein's centre, so a vein's edge can reach up to two blocks over a cave border. Cave tiers are limited to their cave biome and the depths where it lies (the Deep Dark mostly below y −24, the others between 0 and 40).
+- **Surface nodes** (every surface tier): 1–5 ore blocks lying in natural ground (grass, dirt, sand, stone, snow, ...; tag `cobblesurvival:ore_node_ground`), at most one block standing out, never in water or under leaves, a given chance per chunk of the tier's zone. Evolution stones are single blocks and rarer.
- Tiers with an ordinary and a deepslate ore get two veins: the ordinary ore from y 0 up, the deepslate one below.
+- **Cave nodes** (Lush Caves, Dripstone Depths, Deep Dark, Basalt Furnace): a lump on a cave floor in the tier's cave biome, at the depths where that biome lies (the Deep Dark mostly below y −24, the others between 0 and 40). Cave tiers have no veins inside the rock.
 - The companion mod places the nodes (`ore/OreNodes.kt`, table `datapacks/core/data/cobblesurvival/ore_nodes/island.json`) in every new overworld chunk, through the vein mod's own placement, so they are veins like any other and grow back.
 - **Underground veins** (surface tiers): larger (radius 2–4) and fewer than the nodes, generated by the vein mod inside the rock under their zone. A surface zone is a set of boxes cut from the zone grid; the mod checks every vein block against them, so no vein block lies outside its zone; cave biomes are zones of their own, which the veins keep out of (the mod checks the biome at a vein's centre, so an edge can reach a little over a cave border). Tiers with an ordinary and a deepslate ore get two veins: the ordinary ore from y 0 up, the deepslate one below.
 - **Vein Locator**: attuned in the crafting grid with an ore *block* (needs Silk Touch), it finds the nearest vein or node of exactly that block and throws a signal toward it like an Eye of Ender; 75 % chance to break per use. Attuned to the deepslate ore it only finds the deep half of the veins.
 - **Cobblemon's evolution stones are tiers too** (approved for now, 2026-10-30): their natural ores have been off since Phase 1, so stones had no source. Each stone lives in one zone that fits it (Leaf Stone in the jungle, Water Stone in the Mire, Ice and Dawn Stone on Frostpeak, ...).
 - Players can't break regenerators (`allow_breaking` false), so nobody removes a vein for good, and explosions don't hurt veins. The Vein Locator is crafted from a compass and a copper ingot instead of netherite.
- The mod fills a new chunk with veins only while the chunk is loaded, 8 chunks a tick, and forgets the rest when the server stops. Pregeneration is faster than that, so `tools/make_world.py` loads the island again row by row until every chunk is filled (`/cobblesurvival veins unfilled` counts what's left), and the world report fails on any unfilled chunk. On a live server new chunks fill as players load them.
+- Both mods fill a new chunk only while it is loaded, a few chunks a tick, and the vein mod forgets the rest when the server stops.

 **Unique drops.** Only Pokémon live on the island, so a mob's drop needs another source. `tools/drop_audit.py` checks every item a Pokémon or a vanilla mob drops that a recipe or brewing consumes, and writes `docs/pokemon-drops.md` (item, wild Pokémon with zone and chance, other sources, consumers). Gaps it found, filled through Cobblemon species additions (`datapacks/core/data/cobblesurvival/species_additions/`, placeholders): Blaze Rod (Carkol in Westmarch, Torkoal in the Basalt Furnace; needed for brewing stands, blaze powder and Eyes of Ender), Ghast Tear (Drifloon, Dusclops), Breeze Rod (Whimsicott), Shulker Shell (Shuckle, Cloyster), Nether Star (Charizard). The tide armour trim and the wither skeleton skull stay without a source (cosmetic here). A zone spawn with its own drops overrides the species' drops, so the audit also fails if an addition targets such a spawn (Magmortar's and Centiskorch's did). Self-test: `drop_additions_apply`.

 **Catching high-level Pokémon** (Adrian, 2026-10-30). Measured against the trainer's strongest party Pokémon (`catching/Catching.kt`, values in `datapacks/core/data/cobblesurvival/catching/rules.json`):
 - The catch rate falls with the level gap: full at the trainer's level, then linearly down to 2 % of the normal rate at 20 levels above and beyond ("20+ levels higher should be very improbable"). Applied to the rate Cobblemon's catch formula uses (its catch-rate event), so balls, status and HP still count.
 - A failed catch angers the Pokémon: it attacks the thrower instead of fleeing.
 - A wild Pokémon above the strongest Pokémon in a nearby player's party (16 blocks) is hostile to that player.
 - The fighting is [Fight or Flight Reborn](https://modrinth.com/mod/cobblemon-fight-or-flight-reborn)'s: an angry Pokémon gets the aspect `cobblesurvival_enraged`, which the pack's `config/fightorflight.json5` lists in `always_aggro_aspects` (so it fights rather than flees), and its target is set through Fight or Flight's own "caught by" mark, by reflection. While an angry Pokémon has a target, thrown balls don't catch it (Fight or Flight's `aggressive_pokemon_catchable` false, its default): it has to be battled. Pokémon below Lv 5 never fight back (its `minimum_attack_level`).
 - Self-tests: `catch_rate_falls_with_level_gap`, `failed_catch_enrages`, `strong_wild_pokemon_hunt_weak_trainers`, `wild_pokemon_ignore_stronger_trainers`.
 **Bee nests** (found by Adrian in the Phase 4 world): a nest whose bee the island turns away kept the bee and tried to let it out every tick, with its sound each time. The companion mod now empties such a nest (`world/OnlyPokemon.kt`); honey still comes from Combee and shearing nests that have honey.
 The field guide learned two things on the way: vanilla mobs count as absent (the companion mod lets only Cobblemon's entities join a world), and species additions replace the drops they set. The veins come in as sources from `world/vein-sources.json`.

 /**
 * Catching (Adrian, 2026-10-30): high-level Pokémon are hard to catch. Everything is measured against the trainer's
 * strongest party Pokémon:
 *  - the catch rate falls with the level gap, down to a small share at 20 levels above ("very improbable");
 *  - a Pokémon that breaks out of a ball attacks the thrower instead of fleeing;
 *  - a wild Pokémon above a nearby player's strongest Pokémon is hostile to that player.
 *
 * The attacking is Fight or Flight Reborn's: an angry Pokémon carries the aspect [ENRAGED], which the pack's Fight or
 * Flight config lists in `always_aggro_aspects` (so it fights rather than flees), and its target is set through Fight
 * or Flight's own "caught by" mark ([FightOrFlight]). While it has a target, Fight or Flight doesn't let thrown balls
 * catch it (`aggressive_pokemon_catchable` false): it has to be battled. Values: `data/cobblesurvival/catching/`.

Rules: 'within' = distance from 0,0 in blocks; 'biomes' = cells of these biomes, clusters smaller than min_cells dropped, plus 'absorb' = cells of other biomes within that many blocks of the cluster; 'region' = what is left, by half-plane (x/z bounds in blocks); 'water' = sea cells of these biomes. Biomes in 'inherit' (rivers) take the zone of the land around them. Cave zones follow the cave biome everywhere under the island and are not drawn. 'lines' = how many evolution lines tools/zone_spawns.py aims to give the zone (scaled to the lines available); 'species' pins a line to a zone by hand.

'ores': Phase 4 ore tiers for Regenerating Ore Veins (tools/zone_ores.py writes the mod's config from them). Each tier has veins in exactly one zone, higher tiers in higher zones; Cobblemon's evolution stones are tiers too, since their natural ores are off. 'stone'/'deepslate' split a tier into an upper vein (y >= 0) and a lower one; 'blocks' is a weighted list for one vein. 'radius' in blocks, 'y' range, 'spacing' in chunks between candidate chunks, 'regen_minutes' of real time, plus 'jitter' (share of the interval), 'fill' and 'attempts' from 'ore_defaults'. Cave tiers' 'y' follows where their biome lies (the biome preview: Deep Dark mostly below y -24, the other three between 0 and 40), and they get more 'attempts', since each try lands at a random height. 'showcase': the template gets one hand-placed vein of the tier near its zone's sample point (vein '<tier>_showcase': radius 2, never generates by itself). 'level_pressure': a Pokémon more than grace_levels above the band of the zone its trainer stands in gets per_level less experience per extra level, down to minimum (Exp. Candy and commands excepted).",
