Tiles p2p chat sync v1

• Need to add Tiles as a daemon process

Link:

not user facing

• tiles link enable - network open: Creates an endpoint and open for connections.
  • Endpoint will be created using tiles keypair.
• tiles link disable - network close: Close the connection
• tiles link status

Device discovery

• We will use Iroh's [mDNS](https://docs.iroh.computer/connecting/local-discovery) for discovering local devices.
• Iroh's [ticket](https://docs.iroh.computer/concepts/tickets) system to dial the peer.
  • This is a one-time thing as we will cache the endpointID of the peer for further comms in future.
• tiles link - show_ticket: Generate the ticket for dialing
  • Instead of raw ticket, lets do a pair key which is user friendly
• tiles link <BIP39 mnemonic code peer ticket>- Add the peer to local DB.
• Device linking
  • We could share a ucan token to peer which has syncing capability or even wildcard capability for linking the peer together.Sync

Sync

• verify the token u have is capabale of syncing the chats
• provide a command to sync chat and syncing progress cue.
• proper db syncing (naive)
  • receiver sends last chat_id of the sender's chat.
  • sender sends chats which are after that last_chat_id.
  • receiver appends it to their db.
  • vice-versa.
• commands
  • tiles sync
    • syncs local delta to receiver
    • select from a list
