Replace ora with native spinner implementation

Completely removes the ora dependency to eliminate all ESM compatibility issues:
- Created SimpleSpinner class with native Node.js implementation
- No external dependencies, works in all Node.js versions
- Handles TTY and non-TTY environments (CI)
- Maintains same API surface for compatibility
- All 124 tests pass

This is a bulletproof solution that will work in any environment.
