The _is_duplicate_batch check was incorrectly skipping batches based only on comparing ranges to the previous batch. This is wrong because: 1. Proper duplicate detection is handled by state_store.is_processed() in load_stream_continuous, which checks against ALL processed batches 2. The range-only comparison does not check hashes, so batches with same ranges but different data (after reorg) would be incorrectly skipped 3. After crash/restart, prev_ranges_by_network is empty anyway
