Fix critical bugs and Caffeine ClassNotFoundException

- Disabled minimize in shadowJar (was removing Caffeine's dynamic classes)
- Fixed Score.fromString() ArrayIndexOutOfBoundsException
- Fixed Leaderboard DIFFICULTY sort NumberFormatException
- Fixed PAPIHook parsing errors (difficulty, score_until, rank)
- Fixed HoloHook parsing errors (rank, difficulty)
- Added proper error handling for all Integer/Double.parseX() calls
