Optimize repository loading and enhance Git UI

Consolidate multiple Git backend calls into a single bundle to reduce overhead when opening and auto-refreshing repositories. This significantly improves performance by fetching status, branches, commits, and files in one optimized operation, instead of re-running 'git rev-parse' and 'git status' multiple times. Also, streamline commit history loading by fetching file changes inline via 'git log --name-status -z', eliminating expensive per-commit 'git diff-tree' processes. Additionally, introduce the ability to create new branches from a specific commit in the history and refactor the commit comparison feature into a dedicated dialog. The status panel now displays concise file names.
