💾🧩 Feat, Refactor(Debug, Blueprint): 实现蓝图逐步调试UI与数据连接器悬浮值显示

- BlueprintNodeVM 新增 IsExecuting/ExecutionCompleted/IsBreakpoint 状态及 BorderBrushOverride/ThicknessOverride 计算属性
- OnIsExecutingChanged/OnExecutionCompletedChanged/OnIsBreakpointChanged 触发边框重绘通知
- WorkflowEditorWindow 新增 WireUpDebugHighlight，直接操控 Node 控件 BorderBrush/BorderThickness 实现绿色高亮
- BlueprintNodeStyles.axaml 绑定调试高亮到 BorderBrushOverride/BorderThicknessOverride
- BlueprintConnectorVM 新增 RuntimeValue 属性
- BlueprintEditorViewModel.OnDebugVariableChanged 按变量名查找连接器并设 RuntimeValue，结束后清空
- CreateConnectionFromBlueprintConnection 中注册 PubVar 名称至 _variableNameToConnector 映射
- CancelExecution 补设 IsExecuting=false 修复 Stop 按钮状态
- WorkflowEditorWindow.axaml: 连接器 DataTemplate 新增 ToolTip.Tip="{Binding RuntimeValue}"
- WorkflowEditorViewModel 暴露 BlueprintVM.IsDebugging/IsPaused 等调试状态
- AppFramework.RunFramework 重构启动流程：DI→读取日志级别→配置Logger→Load配置→重配Logger
