Why: Intent routing needs a registry of workflow definitions, and uninstall was leaving intents and workflows in place. Evidence: go test ./internal/workflow/ ./internal/plugins/ ./internal/app/ passed. Validation rejects duplicate ids, unknown kinds, denied tools, and both step caps. Unregister clears the registry and the intent gate. Impact: Script steps must stay inside the plugin directory. The server holds the registry for later routing.
