feat: Cloudflare edge caching infrastructure for api.worldmonitor.app#471
Conversation
….app Route web production RPC traffic through api.worldmonitor.app via fetch interceptor (installWebApiRedirect). Add default Cache-Control headers (s-maxage=300, stale-while-revalidate=60) on GET 200 responses, with no-store override for real-time endpoints (vessel snapshot). Update CORS to allow GET method. Skip Vercel bot middleware for API subdomain using hostname check (non-spoofable, replacing CF-Ray header approach). Update desktop cloud fallback to route through api.worldmonitor.app.
