Bram Hagens 60fb59a7a0 fix: display orphan branches separately in commit graph (#10484) ... Fixes #2705. Fixes #7635. This PR fixes the commit graph showing false connections for orphan/root commits. Connection lines are now shown only when a parent/child relationship exists. Visible relationships are determined using `git log`'s `%P` output by the new `ComputeGlyphConnectivity` function. The SVG template is adapted to render vertical lines conditionally. Unit tests for `ComputeGlyphConnectivity` cover regular linear commit history, orphan commits, merge commits, and non-commit glyphs (`|`, `/`, `\`). Unit tests also cover the changes to the `git log` parsing. The SVG template was verified manually.
