ChangesDSE node pinning
Estimated code review effort: 2 (Simple) | ~10 minutes Mergeability Score: 🟡 Moderate · up to The change can pin later DSE steps to the wrong job when the first step cannot be resolved, or stop before obtaining a valid node list, violating the requested first-step affinity behavior. Merge should wait for this bounded correctness issue to be fixed or explicitly accepted; the configuration rename also requires owner awareness if backward compatibility is expected.

runner.jobs is cleared on job completion so was empty when we tried to read it. Store last_submitted_job_id on SlurmRunner at submit time and use it to query sacct for the NodeList after step 1 completes. Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>
runner.jobs is cleared on job completion. Instead of adding a field to the runner, reuse runner.get_job_id() on the stdout file in the output path to find the job ID, then query sacct for the NodeList. Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>

We are basically only restricting it for DSE jobs. We can start with this to unblock ourselves.
But I think even benchmarking or chaining jobs in test scenario can also benefit from this?

fetch_command_output is only on SlurmSystem, not System base class. Use getattr to keep the same defensive pattern as get_job_id. Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Capture nodes only from DSE step 1.
Lines 175-186 retry capture after every unpinned run. If step 1 has no readable job ID or no usable NodeList, step 2 can run unpinned and become the pin source. Later steps then use step 2 nodes, which contradicts pin_nodes_to_first_step.
Record and retry only step 1’s job ID before later execution, or leave pinning inactive when step 1 cannot be resolved. Do not capture nodes from a later step.
