docs(import): expand startWithoutCode use case to the SSH-experiment → run.prepareCommands workflow

Per review on PR #350: startWithoutCode is also the on-ramp for getting a
bare runtime container to SSH into and experiment in, then versioning the
setup steps into run.prepareCommands so they persist across container
replacements (SSH changes alone are non-persistent). Cross-links the SSH
reference and the zerops.yaml run.prepareCommands spec anchor.
