Use walkdir for efficient recursive traversal in FileBackend::build_search_index
- Replace manual recursive directory scanning with `walkdir` for simplified and efficient file traversal. - Update dependencies in `Cargo.toml` and `Cargo.lock` to include `walkdir`. - Enhance code maintainability by replacing redundant logic with streamlined traversal and processing.
