refactor: Migrate from ActivityPub federation to native Swarm network

- Remove ActivityPub infrastructure (webfinger, nodeinfo, inbox, activities, signatures)
- Implement native peer-to-peer Swarm network with gossip protocol
- Replace federated timeline with Swarm timeline aggregating posts from all nodes
- Migrate direct messaging to end-to-end encrypted Swarm Chat system
- Update user interactions (follow, like, repost) to use Swarm protocol
- Add cryptographic key management for DID-based identity system
- Remove server-bound identity model in favor of portable DID identities
- Update documentation to reflect Swarm architecture and capabilities
- Add debug utilities and chat testing tools for Swarm network
- Refactor database schema to support distributed user directory
- Update bot framework to work with Swarm network interactions
- Simplify API routes to use Swarm protocol instead of ActivityPub
- This transition enables true peer-to-peer communication, instant interactions, and encrypted messaging while maintaining sovereign identity through DIDs
