New endpoints:
- GET /pub/outbox — paginated activity feed
- POST /pub/inbox — receive Follow/Accept/Publish from remote servers
- POST /pub/follow — follow a remote sx-pub server
- GET /pub/followers — list accepted followers
- GET /pub/following — list who we follow
Federation mechanics:
- HTTP Signature generation (RSA-SHA256) for signed outgoing requests
- HTTP Signature verification for incoming requests
- Auto-accept Follow → store follower → send Accept back
- Accept handling → update following state
- Publish mirroring → pin remote CID to local IPFS
- deliver_to_followers → fan out signed activities to all follower inboxes
- Publish now records activity in outbox for federation delivery
