feat: inline editing with click-to-edit, TextBox overlay, Focus+SelectAll

- Grid overlay: TextBox covers TextBlock when editing (no more dual display)
- EditValue property: auto-initialized to DisplayName on edit start
- Click on already-selected node enters inline edit (PreviewMouseLeftButtonDown)
- Right-click auto-selects node before context menu
- TextBox IsVisibleChanged: Focus + SelectAll on Loaded priority
- XAML Visibility moved to Style setter (fix DataTrigger precedence)
- Light yellow background (#FFFFFDE6)
