Enhance git change detection by introducing relevant prefixes
- Updated the `git_changed_files_impl` and `collect_untracked_files` functions to accept a set of relevant prefixes, allowing for more targeted change detection. - Modified the `collect_index_worktree_changes` function to filter changes based on the provided prefixes, improving efficiency in identifying tracked and untracked files. - Added a new `known_paths` method to the `RojoTree` struct to facilitate the extraction of relevant directory paths. These changes aim to optimize the detection of changes in the git repository by focusing on specified directory prefixes.
