MetaTLS Transport

transport: metatls — TCP wrapped in TLS (tokio-rustls), with the same framing/ack semantics as TCP.

address syntax: metatls:HOST:PORT

dial / serve:

• ChannelAddr::MetaTls(host, port)

• metatls::dial::<M>(host, port) -> NetTx<M>

• metatls::serve::<M>(host, port).await -> (ChannelAddr, NetRx<M>)

notes:

• Uses Meta cert/key plumbing (/var/facebook/x509_identities/server.pem, env vars like THRIFT_TLS_*).

• See code for details on TLS config and environment integration.
