DuckDuckGo intermittently serves a CAPTCHA modal ("Unfortunately, bots
use DuckDuckGo too...") instead of search results. The result selector
matches zero elements on that page, so callers used to get
([]Result{}, nil) — silent empty results that look like "no matches."
Detect the challenge via the BEM class .anomaly-modal__title and return
a typed ErrBlocked so callers can distinguish blocked from no-results
and react (retry, fallback to another engine, surface to user).

Create exported extractortest package with MockBrowser, MockDocument,
and MockNode that support selector-based responses for testing site
extractors without a real browser.
Add extraction tests for DuckDuckGo (result parsing, empty results, no
links, full search flow) and Powerball (drawing parsing, next drawing
parsing with billion/million, error cases, full GetCurrent flow).
Closes#21
