Drives the WASM FoctetSession (datagram mode) as the handshake
initiator over a real browser WebTransport
against the native webtrans_datagram_split responder (tests.md
§3.5). The authenticated handshake runs over a reliable bidi stream
(length-prefixed control frames); the sealed application data then flows as
WebTransport datagrams (one Foctet datagram frame each).
Start the native server first with the dev cert (from the repo root):
cargo run -p foctet-transport --example webtrans_datagram_split
--features "runtime-tokio transport-webtrans" -- --role server --addr
