fix: resolve GitHub Actions YAML syntax errors

- Fixed indentation issues in performance.yml (all steps now properly aligned)
- Corrected shell script block structure in enhanced-ci.yml
- Fixed missing jobs section and step indentation in optimized-ci.yml
- These fixes should resolve the workflow failures affecting CI/CD pipeline

Addresses the YAML parsing errors that were preventing all workflows from running:
- performance.yml: Fixed inconsistent step indentation
- enhanced-ci.yml: Fixed incomplete if-else block structure
- optimized-ci.yml: Fixed missing proper indentation for steps

All workflows should now pass basic YAML validation.
