discover.py compared the raw OpenAlex cited_id against papers.id (a DOI/arXiv
id), so an ingested paper cited by its OpenAlex id was mis-reported as a
discovery lead. graph.py already resolved this via papers.openalex_id, but the
fix was never propagated — two 'dangling' implementations disagreed.
Extract the resolution into one shared constant RESOLVED_CITATIONS_SQL in
graph.py; build_citation_graph and all four discover.py queries
(discovery_leads / citing_papers / cited_by / cocited_papers) now go through it,
so the 'what counts as ingested' rule cannot drift again.
Live-DB validated: before, 13 ingested papers leaked into discovery_leads;
after, the real discovery_leads() returns 0 ingested papers among its leads.
