Add multi-domain routing: middleware, Redis caching, dynamic renderers
- Migration: Add route column + performance indexes for <5ms lookups - Redis cache layer with graceful degradation - Middleware: Route custom domains to database pages - Page/Post renderers with full SEO metadata - Support for 12-section content fragments - Site-specific styling from config.custom_css Enables: aesthetichelp.com -> database pages Performance: <5ms routing with Redis caching
