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

- Move class attribute after docstring for proper documentation tooling - Simplify metadata to only store end_block and end_hash (remove unused start_parent_hash) - Return False for empty batch_ids in is_processed (align with InMemoryStreamStateStore) - Remove prev_hash from resume watermark BlockRange (was semantically incorrect) - Add comment explaining resume watermark start=end=end_block pattern
