Detect query type (product/concept/opinion/how_to/comparison/breaking_news/
prediction) via lightweight regex patterns and use it for:
1. Source selection: each query type has tier-1 (always run) and tier-2
(run if available) sources. Unlisted sources are opt-in only.
Truth Social is always opt-in regardless of query type.
2. WebSearch penalty: varies by query type instead of flat -15pt.
Concept queries get 0 penalty (web docs are authoritative),
how_to gets 5pt, breaking_news gets 10pt, product/opinion get 15pt.
3. Tiebreaker ordering: source priority varies by query type.
YouTube ranks first for how_to, Polymarket for prediction,
HN for concept queries, X for breaking news.
All changes are backward-compatible: callers that don't pass query_type
get the original behavior (15pt penalty, Reddit > X > YouTube tiebreaker).
