Image Compression Skill

Compress all images in $ARGUMENTS (or app/assets/images/content/ if no path provided) to WebP format, optimized for SEO performance (target: under 100KB per image).

Process

1. Create originals folder - Create originals/ subfolder inside the target directory and move source files there. Never destroy source files.
2. Compress each image (JPG, PNG, GIF) from originals/ to the parent directory as .webp
3. Iterate until all images are under 100KB - check sizes after each pass, re-compress any that exceed the target
4. Report results with before/after sizes
5. Update references in content files from old extensions to .webp
