refactor：AuthScene解耦重构，实现视图与业务逻辑分离
- 创建AuthManager.gd：负责所有认证业务逻辑 - 用户登录/注册逻辑 - 表单验证逻辑 - 验证码管理逻辑 - 网络请求管理 - 创建ToastManager.gd：负责Toast消息管理 - Toast创建和显示 - 动画和生命周期管理 - 支持成功/失败样式 - 重构AuthScene.gd：纯视图层实现 - 只负责UI交互和显示 - 通过信号与业务层通信 - 移除所有业务逻辑代码 - 修复GDScript警告： - 未使用参数添加下划线前缀 - 修复变量名与基类方法冲突 - 修复EventSystem中的try语法错误 - 修复AuthManager中的方法名不匹配错误 符合docs中的架构要求，实现完全解耦

# ============================================================================
|

# ToastManager.gd - Toast消息管理器
|
||||
# ============================================================================
|
||||
# 负责创建和管理Toast消息的显示
|
||||
#
|
||||
# 核心功能:
|
||||
# - 创建Toast消息实例
|
||||
# - 管理Toast动画和生命周期
|
||||
# - 支持多个Toast同时显示
|
||||
# - 自动排列和清理Toast
|
||||
# - 支持中文字体显示
|
||||
#
|
||||
# 使用方式:
|
||||
# var toast_manager = ToastManager.new()
|
||||
# toast_manager.setup(toast_container)
|
||||
# toast_manager.show_toast("消息内容", true)
|
||||
#
|
||||
# 注意事项:
|
||||
# - 需要提供一个容器节点来承载Toast
|
||||
# - 自动处理Toast的位置计算和动画
|
||||
# - 支持Web平台的字体处理
|
||||
