本次更新带来了 NewUI 下的多编辑窗口支持，并同步完成了一批界面与稳定性优化。

主要更新：

• NewUI 现已支持多编辑窗口。
• 编辑窗口支持拖动、缩放、关闭、全屏，以及锁定当前窗口。
• 锁定窗口后，切换到其他角色会新建一个新的编辑窗口；未锁定时则会复用当前窗口。
• 当前激活的编辑窗口会显示完整编辑器，其他窗口会保留对应角色的信息与预览，方便同时管理多个角色。
• 舞台窗口支持自动适应窗口大小，并新增了对应的顶部按钮。
• 扩展选择界面进行了重新整理，搜索、筛选、来源分类和批量导入更清晰易用。
• 批量导入扩展现已支持更合理的导入逻辑，原生扩展会自动使用普通导入方式。
• 修复了 NewUI / 旧 UI 切换时部分 addon 重复加载、消失或显示异常的问题。
• 修复了多个窗口层级、最小化按钮遮挡、窗口拖动偏移、窗口缩放同步等问题。
• 优化了部分编辑器和 addon 的性能问题，减少了不必要的实时刷新和重复更新。

This update introduces multi-editor window support in NewUI, along with a series of UI, stability, and workflow improvements.

Highlights:

• NewUI now supports multiple editor windows.
• Editor windows can be dragged, resized, closed, fullscreened, and locked.
• When a window is locked, selecting another sprite opens a new editor window; when unlocked, the current window is reused.
• The active editor window shows the full editor, while inactive windows keep sprite info and preview content for easier multi-sprite management.
• The stage window now supports auto-fit resizing, with a dedicated top-bar button.
• The extension library UI has been redesigned for a cleaner workflow, with improved search, filtering, source grouping, and batch import.
• Batch extension import now follows better import rules, and built-in extensions automatically use normal import mode.
• Fixed issues where some addons were duplicated, disappeared, or rendered incorrectly when switching between NewUI and the classic UI.
• Fixed multiple window-related issues, including z-index conflicts, minimized button overlap, drag offset problems, and resize syncing issues.
• Improved performance in several editor/addon update paths by reducing unnecessary live refreshes and repeated updates.
