fix: Add missing await for createDemoContext in API routes

- Fixed TypeScript error in stream-dynamic/route.ts
- Fixed negotiate-network/route.ts
- Fixed negotiate-ai-to-ai/route.ts
- Fixed negotiate-dynamic/route.ts
- All createDemoContext calls now properly await Promise resolution

This fixes the Cloud Run deployment build error.
