feat: restructure GPU page layout and simplify content presentation

- Reordered sections to improve information flow (Capabilities → Design → Architecture → Overview)
- Simplified use cases and overview sections by removing redundant bullet points
- Added new GpuCapabilities and GpuDesign components with cleaner, more focused messaging
