Implements modifier system for weapons

Adds a modifier system allowing dynamic modification of weapon
stats and behavior. This includes:

- Creating ModifierLibrary to manage available modifiers.
- Adds ModifierManager to handle equipping and unequipping modifiers
- Adds a new RangedWeaponComponent to handle firing projectiles and
  managing modifiers.
- Introduces a DebugUI for in-game modifier management.
- Introduces an "Unlimited Power" modifier that changes the projectile scene.
- Modifies stats components to work with the new modifier system.

This system allows for more flexible and customizable weapon
functionality.
