feat: refresh product website experience

The website previously buried platform downloads and presented the desktop assistant, Agent Runtime, and broader work capabilities with competing priorities. It now leads with the desktop assistant and AI programming workbench positioning, surfaces cross-platform and domestic Linux compatibility, and uses a responsive interactive product preview with synchronized tilt and soft lighting.

Release note: GoodBuddy 官网现在更清晰地展示桌面助手、Agent Runtime、跨平台与国产化支持，并提供更直观的动态产品预览。
