Decouples core systems from centralized globals in favor of catalogue-based architecture and data-driven content.
Key changes:
- Prestige: node-based buff tech tree, graph panel, progress bar
- Research: multi-worker system, per-generator research, xp generation
- Ascension: meta-currency layer via multi-currency prestige resets
- Buffs: refactored as generator-independent via catalogues
- UI: currency panel, edge-scrolling camera + zoom, current-goal panel
- Alchemy Tower: crafting building with recipe/cost system
- Testing: 7 test suites (ascension, prestige, research, goals)
- Content: migrated from hardcoded idles/ to gym format (tiny_sword)
