Subject: [PATCH] Add delayed separator removal to keep DOM light

- Remove separators (AyRUI, TFQHme) adjacent to already-hidden cards
- Separators removed on next cycle, not immediately (preserves scroll)
- DOM growth reduced by ~50% during long scrapes
- Tested: 2000 reviews in 103s (19.3/s) with all features
