feat: Mark "filter commit" in the view to Make the UI experience better

- Add commit filtering by SHA patterns and track filtered head commits.
- Add property to track if commit is a filter head in commit model.
- Add filter support to commit graph by introducing a new DotType and handling filter head commits.
- Enhance commit querying by adding support for solo commit filters in the history view.
- Add new filter dot type visualization to the commit graph.
