Function sandbox_ssh_proxy_by_name

crates/openshell-cli/src/ssh.rs:1420–1429

Run the SSH proxy in "name mode": create a session on the fly, then proxy. This is equivalent to [`sandbox_ssh_proxy`] but accepts a cluster endpoint and sandbox name instead of pre-created gateway/token credentials. It is suitable for use as an SSH `ProxyCommand` in `~/.ssh/config` because it creates a fresh session on every invocation.
