jakevin 55088bbb28 feat: 13 read adapters across 5 new sites + 4 extensions (round 3) (#1346)
New sites (8 commands):
- npm    : search / package / downloads (registry.npmjs.org + api.npmjs.org)
- pypi   : package / downloads (pypi.org + pypistats.org)
- crates : search / crate (crates.io)
- mdn    : search (developer.mozilla.org)
- nvd    : cve (services.nvd.nist.gov)

Extensions (5 commands; +1 dblp/author surfaced in index):
- hf            : spaces (Hugging Face Spaces by likes / created_at / last_modified)
- dblp          : venue (search dblp's venue registry by acronym/topic)
- coingecko     : derivatives (perpetual / futures markets, 24h volume)
- stackoverflow : related (related questions for a given question id)

All commands hit public unauthenticated endpoints (Strategy.PUBLIC, browser:false),
typed-fail-fast on bad inputs (no silent fallback / clamp), and round-trip listing
ids into their detail commands where applicable.

Audits (all green vs baseline):
- typed-error-lint        : 196 = 196 baseline, no new
- silent-column-drop      : 103 = 103 baseline, no new
- listing-id-pairing      : 13 advisory (was 12; +1 = dblp/venue with no
                            corresponding venue-detail command)

Doc coverage : 120/120 adapter dirs documented (+5 new doc pages, +4 updated)
Manifest     : 722 entries (was 709; +13 commands)

Live verified:
- npm search react / npm package react / npm downloads react --period last-week
- npm downloads react --period 2025-01-01:2025-01-05
- pypi package requests / pypi downloads requests --period recent / overall
- crates search tokio / crates crate serde
- mdn search fetch
- nvd cve CVE-2021-44228
- hf spaces --limit 3
- dblp venue ICLR
- coingecko derivatives --limit 3
- stackoverflow related 79935770 --limit 3
- typed-error sanity: invalid CVE id, bad npm name, bad --period

// npm package — fetch a single package's registry metadata.
//
// Hits `https://registry.npmjs.org/<pkg>` and projects the fields most useful
// for an agent: name, latest version, description, license, homepage,
// repository, bug tracker, maintainers, last-modified time. Download stats
// are intentionally separate (see `npm downloads`) so failure modes don't get
// silently folded into a registry-metadata response.
