merge: reconcile data-quality roadmap with audit-remediation main (#12-15)

Resolved 4 conflicts: cli.py (R-D citing-coverage warning + main's small-corpus JSON/hub-title changes both kept); ingest.py (C-7 paper.id=caller-id pin first, then DQ-2 abstract recovery); test_ingest.py + test_openalex.py (kept both branches' tests).

C-7/DQ-5 overlap (both canonicalise papers.id): kept both layers — openalex._canonical_id normalizes fetch_paper's id (DQ-5); ingest pins papers.id to the caller's bare id (C-7); they converge on the bare canonical id. Fixed the auto-merged test_fetch_paper_success that had contradictory bare/URL assertions. 402 tests pass; ruff + mypy clean.
