- insert_filing: catch IntegrityError on duplicate accession instead of crashing
- filter_new_accessions: bulk pre-filter entire quarter against DB in chunked IN queries
(avoids 30min per-row accession_exists loop during resume)
- mark_accession_seen: store placeholder row for derivative-only/empty filings so they
aren't re-fetched on every resume
- get_recent_buys_for_ticker: accept as_of_date to clamp queries for historical signal gen
- get_all_buys_for_reprocess: return all buy filings ordered by transaction_date for backfill
