feat: Add solo commits filter and enhance history filtering

- Add new filter type for solo commits to the filter options.
- Enhance history filtering to support solo commits by including or excluding their associated refs.
- Add new localization string for solo commits option in context menu.
- Add methods to filter and query commits by solo commit mode and refs containing a specific commit.
- Add a menu option to filter commits by focusing on a specific commit.
