Capture network device config snapshots diffs and change attribution after edits with Oxidized

Use Oxidized when an agent or operator needs to collect, diff, and retain network device configurations across fleets instead of treating it as a generic network management platform. The workflow is specific: fetch configs from supported devices, trigger refreshes after change events, store version history, and inspect diffs or blame when something changed. That scope boundary—configuration backup and drift visibility for network devices—keeps this publishable as a skill instead of a plain product card.
