pub fn connect_or_spawn_server(
channel: &ChannelName,
cfg: &ServerSpawnConfig<'_>,
) -> Result<String>Expand description
Wait for a session server to become reachable on the channel, spawning one
via current_exe() --server if none is running.
Returns the channel name string, which the caller passes to the muxio IPC
client. The client and server both route it through GenericNamespaced, so
no filesystem path is involved.
