Each pick's web page now lists up to five related articles: the nearest
embedded articles across the whole archive (cosine >= 0.55), excluding the
rest of the issue, excerpt-only articles and same-title copies. They are
computed once per issue after publishing and stored in issue_related
(migration 0014), since the full embedding scan is too slow per page view;
`features related [--date]` and the related-refresh job backfill older issues.
Related articles that ran in an issue link to that issue page; the rest link
to a new signed-in /articles/{id} page rendering the stored body with no
summary. /articles/{id} for a published article redirects to its issue page.
embedding_retention_days = 0 now means keep every vector (previously it would
have deleted every unrated, unpublished embedding) and is the new default, so
related lists can reach the whole archive.
