phase 9: biome expansion — 3 biomes, 40 elements, 119 reactions, 9 species

Expand beyond vertical slice with two new biomes and massive chemistry expansion:

Chemistry: +20 real elements (Li→U), +39 compounds (acids/salts/oxides/organics),
+85 reactions (Haber process, thermite variants, smelting, fermentation, etc.)

Biomes: Kinetic Mountains (physics/mechanics themed) and Verdant Forests
(biology/ecology themed), each with 8 tile types and unique generation rules.

Creatures: 6 new species — Pendulums/Mechanoids/Resonators (mountains),
Symbiotes/Mimics/Spore-bearers (forests). Species filtered by biome.

Infrastructure: CradleScene biome selector UI, generic world generator
(tile lookup by property instead of hardcoded names), actinide element category.

487 tests passing (32 new).
