a0.2

In a0.2, SumoGUIMac has become a usable native macOS SUMO viewer for real TraCI workflows. The app can open and run SUMO scenarios, attach to external TraCI sessions, display live moving vehicles with smoother Metal rendering, and provide practical inspection tools for everyday simulation work. This release adds improved zooming and dragging, lane and vehicle colouring modes, object selection and route highlighting, tracker charts, breakpoints, recent documents, screenshot export, vehicle follow/rotate-follow, a FlowDemo example scenario, and early NetEdit/native editing support. It also includes alpha release packaging, GitHub Actions CI, benchmark tooling, Cloudflare landing-page support, improved TraCI subscription/polling behaviour, and a Swift concurrency fix for CI builds. Also, the GUI has been improved to better match the sumogui app.
