feat(cypress): enhance command interface with schema validation methods

- Added new commands for document and DOM schema validation, including methods to assert schema validity and log document structures.
- Updated existing Cypress tests to use strict equality checks for schema validation results.
- Introduced ESLint directive to disable undefined variable warnings in helper.js.
