Player Hitbox

> Build-26.10.1.1.1 (v1.1.1)

• Consolidated the model scale ("1.0 / 0.9375") from individual sub-animations into a dedicated root transform animation ("animation.hitbox.transform").
• Fixed a 0.1-unit gap between the model and the ground by applying a global vertical offset to the "rootHitbox" bone.
• Optimized the bone hierarchy by removing redundant position offsets from "hitboxBottom" and "hitboxPillars", allowing them to inherit their positions directly from the parent "hitbox" bone.
• Cleaned up Molang expressions in "player.entity.json" by removing the obsolete "v.hitbox_offset_y" variable and simplifying top-frame calculations.
