feat: implement CSS sprite system for image optimization
Reduces HTTP requests from 44+ individual images to 3 sprite sheets (~93% reduction). Includes Go sprite generator tool, CSS classes, template integration, and E2E tests. - Add cmd/sprites/main.go for sprite generation (60x60px + 120x120px @2x) - Add _sprites.css with responsive sizing and retina support - Update templates to use sprites with logoIndex fallback - Add Makefile targets: sprites, sprites-clean - Add 9-test E2E suite for sprite functionality - Add doc/22-SPRITES.md with usage documentation
