phase 10: schools — Mechanic, Naturalist, Navigator with unlock system and bonuses

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).
