Documentation and Evidence Changes

• Finalize the v1.1.0 changelog section

Final Workflow Annotation Behavior

The full validation suite retains the 10 documented requirement
mismatches. The final workflow displays one expected Newman exit-code
annotation and one informational notice while the successful CI
smoke/regression suite determines the overall workflow result.

Safety

No Postman collection, environment, GitHub Actions workflow, package,
SQL, spreadsheet, assertion or test-case logic was modified.
