DBetterModel

Feat

• Added bStats metrics integration.
• Added shadow_radius mechanism to control bone shadow size.
• Added billboard mechanism support directly to BMBoneTag.
• New tags: <BMBoneTag.local_position> and <BMBoneTag.real_position>.
• BMModelTag now accepts mechanisms (tint, glow, etc.) to apply changes to the entire model at once.

Refactor

• Optimized bmpart command: skins now load asynchronously and apply immediately (removed artificial delay).
• Updated <BMBoneTag.global_position> to return a standard LocationTag.
• Improved internal rendering logic for better compatibility with BetterModel API.
• Removed forced skin cache clearing to improve performance.
