feat(gitlab_glab): add CI pipeline functionality with glab ci run

- Add new run_ci_pipeline method to GitLabServer class
- Support all glab ci run options including variables, branch, and web mode
- Auto-detect current branch using git branch --show-current when -b is missing
- Implement web mode that overrides CI_PIPELINE_SOURCE=web
- Add comprehensive test coverage with 9 new test cases
- Update README.md with complete documentation and usage examples
- Maintain 95% test coverage and pass all 53 tests
- Follow project standards with proper error handling and type hints

Closes: Add CI job runner functionality as requested
