"""Wiki-enrich API — read-only HTTP wrapper over the wiki_index lookup.

Extraction #5 prep: lets the (future) navi-places service fetch wiki enrichment
over HTTP instead of reading recon's 2.1 GB data/wiki_index.db directly. Additive
only — does not change place_detail's in-process `_enrich_with_wiki_index` path.

  GET /api/wiki-enrich?wikidata=<Qid>          (primary key)
  GET /api/wiki-enrich?name=<name>&country=<cc> (fallback key)

Public (no auth), matching /api/place/*. 400 if no usable key; 404 on no match.
