This PR replaces the external call with a native implementation for the option #1845 Some output samples: Windows Linux

This PR refactors the directory traversal logic in WorkerState to improve readability and maintainability. Previously, the evaluation of filtering constraints (depth, patterns, extensions, size, time) was implemented as a large block of inline conditionals within the core walk loop. This change extracts that logic into a dedicated EntryFilter struct, cleanly separating the traversal mechanics from the filtering rules. All existing traversal behavior and the execution order of the filter checks are strictly preserved. Changes This PR cleans up the walk entry processing so the main loop is easier to read and reason about. Moved file filtering logic into a new helper, with separate methods for pattern, size, owner, and other checks. Added to handle conversion, broken symlink recovery, and walker errors outside of the main loop. Moved Unix-specific owner-check logic into , keeping the main path less cluttered with platform-specific conditionals.
