v3.1.0

Highlights

• Added project-based font collections with atomic runtime application and improved Godot-side font shaping and fallback.
• Refactored the coordinate system by separating logical and render coordinates and centralizing coordinate conversion across SPX and Godot.
• Optimized pen GPU rendering by batching pen state updates, reducing Web bridge calls, and synchronizing the pen canvas with stage geometry.
