Disable Biome useConst rule permanently + fix all const violations

CRITICAL FIX: Biome was auto-converting let to const in pre-commit hook
- Added useConst: off to biome.json
- Fixed all Svelte files again (RetroInput, ModernJourneyFull, etc.)

This prevents Svelte 5 reactivity breakage permanently.
