feat(news): rank this company's news first and label each item

Browse source 
MSN's feed for a stock is often mostly general market news: of 10 items,
ADRO, BREN and CUAN had none about the company, BBRI one, yet they were
presented as the company's news. Fetch at least 50 items, label each
`relevance: company` (tagged by MSN with the stock's instrument id, or
naming the ticker or the company) or `market`, and return company items
first, newest first, trimmed to --limit.

Company names come from the quote's short and display names, best
effort: MSN tags Telkom articles with its NYSE ADR, not TLKM, so names
catch what tags miss. Classification stays a pure function in parse_news.

Output change, intentional: news JSON gains `relevance`, the table an
ABOUT column (goldens regenerated), and the get_company tool description
explains the field (tools.json and the website tools page regenerated).
News cache keys change so entries without the field are not reused.
