Mcedia Core

这是相对于旧版 Mcedia 的重构，不是兼容性的增量版本。

• 移除了基于 armor stand（盔甲架）的播放器交互模型。
• 调整为只承载播放器核心能力的 Core Mod。

This is a refactor relative to the old version of Mcedia, not an incremental release focused on compatibility.

• The player interaction model based on** armor stands has been removed.**
• Refactored into a Core Mod that only carries the player's core capabilities.
