Minor Changes

• 8f724a7: feat: add externalSystem flag to services for modelling third-party integrations

  Services can now set externalSystem: true in their frontmatter to be rendered as external systems. This changes their presentation without changing their capabilities — they still send and receive messages, have owners, and support specifications like any other service.

  • Visualiser: external services render purple with a Globe icon and an "External System" badge
  • Sidebar (root): a dedicated "External Systems" section lists externals; the regular "Services" section excludes them
  • Sidebar (domain): externals appear under a new "External Integrations" group, separate from "Services In Domain"
  • Per-service nav badge reads "External System" instead of "Service"
  • /discover: a new "External Systems" tab alongside the "Services" tab
  • SDK: the Service type now accepts externalSystem?: boolean
