fix: resolve TypeScript linting errors preventing CI pass

- Removed invalid workflow property from createTestTemplate function
- Fixed TemplateWorkflow interface usage to use nodes directly
- Removed unsupported watchExclude property from vitest config
- Updated seedTestTemplates to properly handle template data structure

All TypeScript errors are now resolved.
