Large directory scans stop freezing the interface

Scanning big directory trees no longer freezes the interface for seconds.

What

Directory walks and the upload file filter now pause to let the interface redraw at least every 200 ms, and cap how many file operations run at once. Scanning a big tree should no longer block the UI for seconds or open an unbounded number of concurrent reads.

Details
  • A shared limiter provides both the yield budget and the concurrency queue; the walk and filter paths each set their own maximum concurrency.
  • Applies on those paths unconditionally, with no setting to turn it off.
