+The prompt file is always copied (so the in-guest path always
+exists) but `--append-system-prompt-file` only fires when the
+agent actually has a prompt — the return value signals which
+case, mirroring the docker backend's contract.
+
+`smolvm machine cp` lands files as root inside the VM; the claude
+process runs as `node`, so we chown + chmod the prompt after the
+copy. Same flow as the docker backend's provision_prompt."""
