Summary: Package and configure scontrol_topology as a single-node systemd service that collects and publishes Slurm topology every 60 seconds. Add Debian packaging and operator documentation while leaving exporter-specific routing in deployment configuration. Test Plan: Static checks: git diff --check; black --check and flake8 on gcm/tests/test_scontrol_topology.py; TOML, Python syntax, systemd-analyze, and Debian packaging verification. End to end: deployed the GCM build to a development Slurm cluster, ran a live one-shot topology collection through the configured telemetry pipeline, and confirmed fresh rows in the target dataset with the expected topology fields and node counts.
