More Difficult Wither Storm

Rewrote the anti-gravity entity system: unified GravityReversalTransform and reworked entity states, AABBs, landing detection, dropped items, experience orbs, TNT, falling blocks, arrows, projectiles, and more. Complete camera adaptation: Reversed the camera, then added partialTick and interpolation from eyeHeightOld to eyeHeight to resolve Y-axis jitter and crouching camera angles. Continued adapting player and entity rendering, including death animations in the reversed state. The Sweeping Blade was reworked from a simple coordinate correction to an independent mdws:gravity_sweep_attack particle, finally resolving the display issue when performing the Sweeping Blade attack while upside down. Attempted to adapt a large number of particles: status effects, death poofs, animal particles, critical hit/enchanted attack TrackingEmitters, DAMAGE_INDICATOR, etc.; however, this portion was not fully resolved and has been postponed to 1.2.7. Fixed issues such as “Command Block equipped with an anvil displaying ‘Too Expensive’.” Adjusted the attack range of command block enchantment books; they now target Vanilla Wither/Wither Skeletons as well as LivingEntities in CWSM/MDWS. Compatibility fixes related to Wither Storm star drops and the final phase.
