Jamey Greenwood 2bc05097b9 feat: enhance image optimization with on-demand JPEG fallbacks
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.
