-# Container-based agent-network end-to-end suite (build tag `e2e`). It stands up
-# the combined server + proxy + a NetBird client in Docker and drives live
-# chat-completions through the gateway, so it is slow, needs Docker, and needs
-# provider credentials. It is therefore NOT part of the normal CI; run it
-# manually via the Actions tab. Provider scenarios skip when their secret is
-# absent, so the suite still runs (management-side scenarios) without keys.
