Downloads Printify CDN images via ImageDownloadWorker, processes
through Media pipeline (WebP conversion, AVIF/WebP variant generation),
and links to ProductImage via new image_id FK.
- Add image_id to product_images table
- ImageDownloadWorker downloads and processes external images
- sync_product_images preserves image_id when URL unchanged
- PreviewData uses local images for responsive <picture> elements
- VariantCache enqueues pending downloads on startup
- mix simpleshop.download_images backfill task

Improve the image optimization pipeline with better compression and
smarter variant generation:
- Change to_lossless_webp → to_optimized_webp (lossy, quality 90)
- Auto-resize uploads larger than 2000px to save storage
- Skip pre-generating JPEG variants (~50% disk savings)
- Add on-demand JPEG generation for legacy browsers (<5% of users)
- Add /images/:id/variant/:width route for dynamic serving
- Add VariantCache to supervision tree for startup validation
- Add image_cache to static paths for disk-based serving
The pipeline now stores smaller WebP sources and generates AVIF/WebP
variants upfront, with JPEG generated only when legacy browsers request it.

Convert mockup source images from JPG to WebP format for 76% size
reduction (20MB → 4.7MB). Variants are now auto-generated on startup
via Oban, keeping the same DRY approach as database images.
Changes:
- Add OptimizeWorker.enqueue_mockup/1 for filesystem images
- Extend VariantCache to check mockup sources on startup
- Update MockupGenerator to save source as optimized WebP
- Update .gitignore to ignore generated variants
- Convert 55 source mockups from JPG to WebP
The mockup pipeline now uses the same code paths as database images:
- Optimizer.to_optimized_webp/1 for source conversion
- Optimizer.process_file/3 for variant generation
- OptimizeWorker for Oban background processing
- VariantCache for startup cache validation

- Add Optimizer module with lossless WebP conversion
- Generate responsive variants at [400, 800, 1200] widths
- Only create sizes <= source dimensions (no upscaling)
- Support AVIF, WebP, and JPEG output formats
- Add disk cache at priv/static/image_cache/
- Add comprehensive test suite (12 tests)
- Add image fixtures helper for testing
