D-04: add _make_bibkey(paper) — ConcatSurnames+Year, ≤3 authors full list,
>3 authors FirstEtAlYear. Applied in ingest_paper when paper.bibkey is
None. ON CONFLICT now fills NULL bibkeys via COALESCE(papers.bibkey,
EXCLUDED.bibkey) while preserving manually-set values.
D-05b: add codex/__main__.py so `python -m codex` dispatches to the CLI.
D-05c: fix test_ingest.py:75 — rename var to raw_api_citations (the raw
OpenAlex payload with citing_id=openalex_id) and add regression
assertion: citing_id written to DB must equal paper.id (DOI), not
paper.openalex_id.
D-05a (proxy): add TestEntryPoint.test_python_m_codex_help — runs
`sys.executable -m codex --help` via subprocess, covering the
non-uv-run entry path. 253 tests green, ruff+mypy clean.
