Add System Stats Section at the Bottom of the Window

Description:
We need to create a section at the bottom of the window to display system statistics, including GPU and CPU information, as well as memory usage. The section should show real-time data for the following:

• GPU type
• GPU architecture
• GPU usage percentage
• GPU VRAM usage / VRAM capacity
• CPU type
• CPU usage percentage
• RAM usage / RAM capacity

Tasks:

1. Design the system stats section:

   • Add a section at the bottom of the window to display the system stats.
   • Ensure the section is non-intrusive and blends well with the existing UI design.

2. Gather system statistics:

   • Implement functionality to retrieve GPU information:
     • GPU type (e.g., NVIDIA RTX 3090)
     • GPU architecture (e.g., Ampere)
     • GPU usage percentage
     • GPU VRAM usage and VRAM capacity
   • Implement functionality to retrieve CPU information:
     • CPU type (e.g., Intel i7-12700K)
     • CPU usage percentage
   • Implement functionality to retrieve RAM information:
     • RAM usage and total RAM capacity

3. Display the data in the system stats section:

   • Show each statistic with appropriate labels (e.g., "GPU Usage: 45%").
   • Format memory usage as Used / Total (e.g., "VRAM: 4.5 GB / 8 GB").
   • Update the stats in real-time to reflect current system usage.

4. Implement refresh/update logic:

   • Ensure that the statistics are updated at regular intervals (e.g., every second).
   • Optimize the update process to avoid excessive CPU usage or stuttering.

5. Testing:

   • Test the system stats section on different hardware configurations (various GPU/CPU types) to ensure compatibility.
   • Verify that the data displayed is accurate and updates in real-time.
   • Test the layout to ensure the stats section remains consistent across various window sizes and resolutions.

6. Update documentation:

   • Document the new system stats section, explaining what information is shown and how often it updates.
   • Add troubleshooting information for potential issues (e.g., missing stats on unsupported hardware).

Acceptance Criteria:

• The system stats section appears at the bottom of the window and shows the requested statistics.
• The stats are updated in real-time, with refresh intervals that do not cause lag.
• Information is displayed accurately and is formatted clearly.
• The UI remains consistent and non-intrusive, even on smaller screens.
• Documentation is updated to explain the new feature.

Additional Context:

• The project uses ImGui for UI rendering, and the system stats section should integrate smoothly with the existing interface.
• Platform-specific methods may be needed to retrieve GPU/CPU/RAM information, so ensure cross-platform support (Linux, macOS, Windows).
