+// Tests for the docker-manager barrel module.
+//
+// docker-manager.ts re-exports the public API from several focused modules
+// (host-env, config-writer, container-lifecycle, container-cleanup). Those
+// modules have their own dedicated test suites; this file verifies that the
+// barrel module itself correctly re-exports every expected symbol and that
+// each symbol has the expected shape (function). This exercises the barrel's
+// export statements for coverage purposes without duplicating the underlying
+// module tests.
