feat: 12 read adapters across 6 new sites + contract tests (round 7) (#1350)
* feat: 12 read adapters across 6 new sites + contract tests (round 7)
New sites: wikidata, lichess, rest-countries, nuget, flathub, oeis
- wikidata: search (wbsearchentities) + entity (Special:EntityData) — Q/P/L ids,
localised label/description with English fallback
- lichess: user + top (perf rankings) — closed accounts → EmptyResultError, no
silent disabled rows; 13 perf types validated
- rest-countries: country (substring) + region — population-sorted by default,
flattened languages/currencies/capitals
- nuget: search + package (full version history) — registration page-walking
for 100+ version histories; case-insensitive id with strict shape gate
- flathub: search + app — appId reverse-DNS, dual-shape timestamp coercion
(search is unix-seconds int, /appstream is ISO string)
- oeis: search (paginated) + sequence — A-id zero-padded, 12-term preview with
(+N) suffix, surfaces commentCount/formulaCount/etc instead of full graphs
Contract tests: 6 files × 7 assertions = 42 contract assertions, all green.
Live verified all 12 commands against real APIs.
Audits clean: typed-error 196=baseline, silent-column 103=baseline, 0 Round-7
listing-id-pairing violations (all 6 listings carry round-trip ids).
* fix(nuget): fail fast on malformed registration pages
