Refactor Live2D plugin and renderer for improved clarity and performance

Browse Source 
- Updated EGL and OpenGL ES integration in gl.rs for better context management.
- Simplified error handling and logging in model.rs and plugin.rs.
- Enhanced texture handling and rendering logic in renderer.rs.
- Added a script to find Cargo configuration files for easier debugging.
- Removed unused imports and dead code to clean up the codebase.

//! OpenGL ES 2.0 / EGL 渲染后端
//!
//! 使用 EGL 创建离屏 PBuffer 上下文（无窗口），用 OpenGL ES 2.0 渲染 Live2D 模型。
//! 渲染结果通过 glReadPixels 读取，交给 video 插件或直接显示。
//!
//! 这里采用 X11 窗口方式渲染（设备有 X11 + kwin），直接显示到屏幕。
//! 如需离屏渲染可改为 PBuffer。
//! 使用 EGL + X11 窗口创建渲染上下文，用 OpenGL ES 2.0 渲染 Live2D 模型。
