- Added DownDash ability with cooldown and speed configuration. - Introduced DownDashState to handle down dashing mechanics, including gravity manipulation and animation playback. - Updated PlayerMovement to support DownDash functionality. - Enhanced PlayerStats to manage spring charge consumption and healing. - Modified PlayerCombat and WeaponHitBoxInstance to support new hit confirmation events. - Updated AbilityType to include new form types for character abilities. - Improved Gizmos for better visualization of enemy detection and attack ranges. - Added feedback systems for form switching in PlayerFeedback and IFeedbackPlayer. - Refactored combat and movement states to accommodate new abilities and ensure smooth transitions.
