fix: enhance image reference detection and optimize image processing

- Added support for detecting file URLs in prompts using fileURLToPath for accurate path resolution.
- Updated image loading logic to default to JPEG format for optimized image processing.
- Improved error handling in image optimization to continue processing on failures.
