Polling watcher no longer thrashes HDDs on Docker Desktop
If you run Calibre-Web-NextGen on Docker Desktop (Windows or macOS) with a large ingest folder on a spinning HDD, you've probably noticed constant drive activity even when nothing's happening. Inotify doesn't work for bind-mounted host directories on those platforms, so the watcher falls back to polling — and the fallback was walking the entire ingest tree every 5 seconds, stat'ing every file.
Now there's a cheap directory-mtime gate: if nothing has been added or removed since the last poll, the watcher skips the walk entirely. On a 3000-book HDD library that means going from thousands of stat calls per poll down to a handful. New files still get picked up on the next poll after they land.
Zero behavior change if you're on a system where inotify works.

Originally reported on the upstream tracker at crocodilestick/Calibre-Web-Automated#1360. Reproduced in this build before fixing; verified the gate doesn't break new-file detection.
