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.
