feat: update ngit init for non-interactive mode

Complete rewrite of ngit init to support non-interactive mode by default.
Key changes:
- Implement hybrid validation (validate all args upfront, fail fast)
- Add --grasp-servers flag for specifying git servers
- Prefer --name over --identifier for better UX
- Add comprehensive validation with helpful error messages
- Support both clone and init-from-existing-repo workflows
- Add --force flag to bypass safety checks
- Update tests for new non-interactive behavior
- Add test utilities for non-interactive testing
