Effectification [Effect Unification]

Added

• Added debugLogging config option for troubleshooting
  • Disabled by default
  • Shows effect conversion and cache operations when enabled

Fixed

• Fixed compatibility with custom StatusEffectInstance subclasses (Majrusz's Difficulty and similar mods)
• Fixed hasEffect() returning incorrect results during effect application
• Fixed removeStatusEffect() not working in unidirectional mode
• Fixed infinite loops when source equals target effect

Performance

• Improved effect ID caching (3 separate caches merged into 1 shared cache)
• Optimized ThreadLocal operations (changed remove() to set(false), cached get() results)
• Added instance-level caching for effect type and amplifier conversions
• Added static lookup cache for hasEffect/getStatusEffect operations
• Cache automatically clears on config reload
