Release 6.0.0: add portable support and docs

Bump release to 6.0.0 and add portable build/support. Changes include:

- Update version string in installer (albayan.iss), program constants (utils/const.py), setup defaults and environment fallback (setup.py), and documentation generator defaults (documentation_creater.py).
- Add portable packaging step in GitHub Actions: copy build into portable_output\Albayan before zipping.
- Add portable-related UI behavior in main.py: display program name as Installed/Portable/Source.
- Expand UserGuide and WhatsNew (HTML/MD) to document portable downloads, creation, storage differences, additional requirements (MSVC redistributable), and acknowledgements.
- Remove utils/mode.py (registry/installed detection implementation replaced or relocated).

These changes prepare and document the 6.0.0 release with official portable distribution support and related UX/docs updates.
