Subject: [PATCH 2/2] Implement Hex Data Transcoder with C boot-code export
- Added bidirectional image-to-hex and hex-to-image conversion.
- Added 'C Source Export' for freestanding OS*2 boot logo customization.
- Generated C code includes ARGB8888 data and centering logic.
- Updated site navigation to include the new Converter tool.
- Verified with automated Playwright tests and visual screenshots.
