Release v0.0.0.6

- Try GetActiveObject first, then Activator.CreateInstance as fallback
- Use Type.GetTypeFromProgID for version-independent COM activation
- Clear error message explaining possible causes including New Outlook
- NuGet Interop v15 is fine - it's the assembly version, works with
  all Outlook versions (2013-2024) via COM interface compatibility
