dsh-plugin-check: DSH Plugin Repository Read-Only Health Check

The DSH networking tool plugin maintained by omdsh-dev registers a plugin_check tool that performs read-only static scanning on the plugin repository. It covers 33 checks including manifest protocols, patch formats, build pitfalls, and hub inclusion, outputting a JSON compliance report. It supports three actions: check, scan, and schema. It is recommended to install via Profile Bundle to a web or headless profile, suitable for author self-inspection and CI gating.
