Added a detailed specification for CDN functionality, including:
- Lightweight CDN node concept (simple executable for users)
- Secure connectivity using pre-shared keys
- Dynamic registration with main metadata server and DNS assignment
- Content awareness, replication, and streaming fallback
- Peer-to-peer (P2P) sharing for distributed content transfer
- Federation and collaboration between CDNs
- Future idea: predictive caching based on user activity
This formalizes the CDN architecture for Walros, supporting distributed caching,
federation, and smarter prefetching mechanisms."
