Function scan_directories

src/classmap_scanner.rs:167–180

Build a classmap by scanning all `.php` files under the given directories. Each directory is walked recursively using the `ignore` crate for gitignore-aware traversal. Hidden directories (`.git`, `.idea`, etc.) are skipped automatically. Directories in `.gitignore` are also skipped. Any directory whose absolute path is in `vendor_dir_paths` is explicitly skipped regardless of `.gitignore`. Fi

/// class name appears in multiple files, the first occurrence wins.
