Detailed Description

Adapts the BTNodeGraphManager + NodeGraphPanel to IGraphRenderer.

Phase 2 Enhancement: Now includes split-panel layout with:

75% NodeGraphPanel (canvas rendering)
25% Right panel with tabs:
- Tab 0: BTNodePalette (node selection + drag-drop)
- Tab 1: BTNodePropertyPanel (node property editing)

Each instance manages a single BT graph ID in BTNodeGraphManager. When Render() is called, this renderer sets that graph as the active one and delegates to a shared NodeGraphPanel reference for drawing.
