Add 3 new schools with real scientific principles (Lever & Moment, Photosynthesis,
Angular Measurement). Data-driven unlock conditions check codex elements, creature
discoveries, and completed runs. Each school provides passive gameplay bonuses
(projectile damage, movement speed, creature aggro range, reaction efficiency)
applied through system multiplier parameters. CradleScene shows all 4 schools with
locked ones grayed out and showing unlock hints. 24 new tests (511 total).

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).

UIScene renders as overlay on top of GameScene:
- Health bar (top-left) with color transitions green→yellow→red
- 4 quick slots (bottom-center) with active highlight, item symbols and counts
- Inventory weight/slots info (bottom-right)
- Controls hint (top-right)
GameScene pushes state to Phaser registry each frame.
Phase 4 (Player Systems) complete — 222 tests passing.

- bitECS world with time tracking (delta, elapsed, tick)
- 5 components: Position, Velocity, SpriteRef, Health, ChemicalComposition
- Movement system (velocity * delta) + bounce system (boundary reflection)
- Health system with damage, healing, death detection
- Entity factory (createGameEntity/removeGameEntity)
- Phaser bridge: polling sync creates/destroys/updates circle sprites
- GameScene: 20 colored circles bouncing at 60fps
- BootScene: click-to-start transition, version bump to v0.2.0
- 39 ECS unit tests passing (74 total)
