## Why

The current ImGui interface uses the default font, which may not provide the best readability and modern aesthetics. Changing to Inter, a popular and highly readable typeface designed for user interfaces, will improve the overall user experience and visual appeal of the USD Layer Manager application.

## What Changes

- Update ImGui font initialization to load and use the Inter font face instead of the default font.
- Add Inter font file to the project resources.
- Ensure the font is properly loaded at application startup.

## Capabilities

### New Capabilities
- `inter-font-setup`: Configure ImGui to use the Inter font for improved UI readability and aesthetics.

### Modified Capabilities
<!-- No existing capabilities are being modified -->

## Impact

- UI rendering system will use Inter font, affecting all text display in the application.
- Requires adding Inter font file to project assets.
- No breaking changes to APIs or existing functionality.
