Check Valid Git Directory by Comparing Top-Level Path

[threeal]

This issue suggests modifying how to check if a directory contains a Git repository by comparing the Git top-level path with the directory path. This change is proposed because merely checking the Git status or if a path is inside a Git directory is not sufficient. Since this project itself is within a Git repository, any directory or files within this project will be considered inside a Git directory. Therefore, comparing the top-level paths is a better approach to determine whether a directory contains a Git repository or not.
