fix(bib): elink snowball merged all seeds into one LinkSet; criteria clause (f) for code-family arm (refs #652)

elink_cited_by sent seed PMIDs as one comma-joined id param, which
makes NCBI elink merge every seed into a single LinkSet — all citing
articles were attributed (and, in the palliative-rfi run, tagged) to
the first seed only. id now repeats per PMID so each LinkSet maps to
its own seed; the 2026-08-18 palliative snowball was re-run with
per-seed attribution (328 articles) after stripping the
mis-attributed tags.

Also adds review-question clause (f) to the palliative-rfi criteria
(records informing the proposed code family's descriptors are
includable) — synced to the live Zotero criteria anchor.
