feat: add skip_build option to macOS workflow for faster universal binary creation

- Add workflow_dispatch inputs to skip build and use previous artifacts
- Add conditional logic to download artifacts from previous runs
- Support both specific run_id and latest successful run
- Significantly reduces build time when only universal binary is needed
