Rebuild the Editor History tab as a one-line-per-commit table with a
branch-coloured lane graph, draggable columns and table/detail divider
(persisted in localStorage), a branch filter, an uncommitted changes row,
keyboard navigation, auto-load, context-menu copy, and a detail panel with
the message body, parents, and per-file added/removed counts.

Rust: git_view_history takes an optional validated branch ref, new
git_view_branches, and commit diffs carry the body, author email, committer,
and numstat counts.
