Refactor code for improved readability and consistency

- Simplified the formatting of path handling in `change_processor.rs` and `fs_snapshot.rs` by consolidating multiple lines into single lines for better clarity.
- Updated test assertions in `two_way_sync.rs` to streamline the code and enhance maintainability.

These changes enhance the overall readability of the codebase, making it easier to manage and understand.
