Pull request overview
This PR improves image compression for LLM interactions by switching from PNG to JPEG format with quality 85, and increasing the maximum dimension from 768px to 1024px. These changes reduce image sizes significantly, allowing ~85 images per conversation instead of 12.
Changes:
- Extracted image processing logic into a new
prepare_image_for_llmhelper function - Changed image encoding from PNG to JPEG with 85% quality
- Updated dimension constraints from 768px max width to 1024px max dimension (handles both width and height)
- Added JPEG feature to the
imagecrate dependency

Missing import statement for the image crate. The code uses image::codecs::jpeg::JpegEncoder and image::ColorType::Rgb8 but there's no use image::... import at the top of the file. Add use image; to the imports section (around line 1-30) to fix the compilation error.

Summary
Reduces the size of the images we send to the LLM. Should allow us to have 85 images in a conversation instead of the current 12 or less
