feat(gitlab): add comprehensive GitLab CI/CD pipeline support

This commit adds full support for GitLab CI/CD pipelines:

- Add GitLab CI pipeline models with complete spec support (jobs, stages, artifacts, cache, etc.)
- Implement GitLab CI/CD pipeline parsing and validation
- Add schema validation against GitLab CI JSON schema
- Support automatic pipeline type detection based on filename and content
- Add GitLab-specific CLI commands and flags
- Implement pipeline conversion for executor compatibility
- Add validation for common GitLab CI configuration issues
- Update CLI help text to reflect GitLab CI/CD support
- Support listing both GitHub and GitLab pipeline files

This expands wrkflw to be a multi-CI tool that can validate and execute both GitHub
Actions workflows and GitLab CI/CD pipelines locally.
