iroh uses RFC 7250 raw Ed25519 public keys for TLS instead of X.509
certificates. rustls already supports this. This means the quinn
endpoint can also use raw public keys — same key-based identity model
as iroh, but with direct QUIC over UDP. X.509 is optional, needed
only for domain-facing identity (browser/WebTransport clients).
Update StaticConfig with TlsIdentity enum (X509, RawKey, SelfSigned)
and add iroh_relay field. Remove 'iroh deferred' language — iroh is
a first-class connectivity mode.
