 - Use `parentMenuItemCode` and `menuItemOrdering` to model the intended CRM page/menu hierarchy.
 - Breadcrumb-like navigation is derived by CRM from the page/menu hierarchy passed in the extension config; do not hand-roll breadcrumbs in the page unless the product task explicitly asks for local in-page navigation.
 - For updating an already installed module, use the existing integration module edit/update flow and put pages under `integrationModule.integrations.embedJs.pages`.
