Peer Sync with convex.world

[mikera]

Should be possible to launch a private Peer locally with a single CLI command and have it sync automatically with the convex.world network

Design notes:

• Private Peer should not require a public open port
• Private Peer may not yet be registered on-chain (in which case it can follow, but not contribute to consensus)
• Should check Initial state hash to ensure compatibility with Peer it connects to
• Default connection should be to "convex.world" well-known port unless otherwise specified
