jakevin a78ceb1602 feat: 11 read adapters across 8 sites (round 2) (#1345)
* feat: 11 read adapters across 8 sites (dblp / steam / bbc / devto / lobsters / medium / coingecko / hf)

Round 2 of the adapter expansion sweep. All 11 commands hit public APIs (no
browser, no auth), follow the post-#1332 typed-error / no-silent-failure
discipline, and were live-verified against real endpoints.

New adapters:
- dblp/author      : recent publications for one author (resolve PID by name, or pass --pid)
- steam/search     : storefront name search (storesearch API)
- steam/app        : single app detail (appdetails API; HTML entities decoded)
- bbc/topic        : per-topic RSS (8 canonical BBC News feeds)
- devto/latest     : /api/articles/latest with --page pagination
- lobsters/domain  : stories from a specific source domain (/domains/<d>.json)
- medium/tag       : tag RSS (description full-length, no silent truncation)
- coingecko/exchanges  : trust score + 24h BTC volume leaderboard
- coingecko/categories : sector buckets with 6 sort options
- coingecko/global     : aggregate market totals + BTC/ETH dominance
- hf/paper         : single-paper detail by arXiv id (summary, ai_summary, ai_keywords, upvotes)

Also adds clis/steam/utils.js + clis/bbc/utils.js as shared helpers (HTML entity
decode, RSS parsing). All listings carry a round-trippable id where a detail
sibling exists; advise:listing-id-pairing reports zero new violations. typed-
error-lint and silent-column-drop gates both unchanged from baseline.

Manifest: 698 → 709 (+11 entries).

* fix: tighten adapter round2 contracts

// bbc topic — BBC News headlines for a specific category, via public RSS.

// BBC publishes per-section RSS feeds at

// canonical sections and reject anything else with a typed argument error
