Proof-of-concept mesh agent library over iroh

Browse Source

Working library with real iroh connections, not an interface sketch:

- persistent device identity in state.sqlite, stable across restarts
- deterministic network space derived from name + secret via HKDF-SHA256,
  with frozen labels and unambiguous length-prefixed encoding
- replaceable discovery returning unverified candidates only; static
  bootstrap, in-memory test backend and a composite
- real iroh connections plus an explicit mutual membership proof:
  HMAC-SHA256 over a role-separated transcript bound to the TLS exporter,
  the network id and both endpoint identities
- small versioned control protocol: handshake, announcement, ping/pong
- multiple networks per agent with enforced isolation
- automatic reconnect with bounded backoff and jitter
- mandatory state vs disposable cache, with a real directory ownership lock
- status snapshots, event stream and honest diagnostics

47 integration and unit tests cover the required scenarios offline on
loopback. Snapshots, revocations and WireGuard are designed for and
documented, not implemented.
