Subject: [PATCH] =?UTF-8?q?test:=20end-to-end=20handshake=20=E2=80=94=20dr?=
 =?UTF-8?q?iver=20uses=20ChatClient::connect=20/=20Dispatcher::serve?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Bumps comline-codegen-rust to comline-rust main (through #6, the handshake
codegen) and switches the end_to_end driver from `Client::new` /
`Server::serve` to the generated `ChatClient::connect(transport, MsgPack)`
and `ChatDispatcher(svc).serve(&mut transport, MsgPack)` helpers — so the
connection handshake (IR_HASH + format name, exchanged + checked) runs
through the whole schema -> CLI -> compile -> run pipeline.

Also picks up #5 (@timeout_ms codegen).
