      description: Fetch the current session identity token for a captain thread. The caller must have access to the project that owns the thread. The same token is also written inside the captain VM to `/etc/capy/session-token` with permissions `0600`, so code running inside the VM can read it locally. A `410` response means the session has already ended. A `422` response with code `session_not_ready` means the token has not been minted yet during initial bootstrap; retry with backoff.
