-Documented the explanatory-output-style plugin updates in the smoke workflows, including marketplace URL syntax, schema support, and MCP configuration guidance so the new plugin is tracked in the release notes.
+Fixed plugin import format in smoke workflows from marketplace URL syntax (`explanatory-output-style@claude-plugins-official`) to GitHub repository path (`anthropics/claude-code/plugins/explanatory-output-style`). The marketplace URL format was not recognized by the Copilot CLI, causing smoke test failures. Updated documentation and schema to clarify that plugins must use GitHub repository paths.
