+ * Test for dispatch_workflow tool registration in HTTP server
+ *
+ * This test validates that the HTTP server correctly registers dispatch_workflow tools
+ * that have _workflow_name metadata. These tools use workflow-specific names
+ * (e.g., "test_workflow") while the config key is "dispatch_workflow".
+ *
+ * Reference: Issue where dispatch_workflow tools were not being registered because
+ * the HTTP server's registration loop only checked if the tool name matched a config key,
+ * but dispatch_workflow tools don't match - they have workflow-specific names with metadata.
