- Add webscraper_search_hint() tool using Brave Search as backend (no CAPTCHA/GDPR consent wall, works with plain httpx) - Add User-Agent header to _fetch_page() — fixes 403 on Wikipedia, Feynman Lectures, and other sites that block headless requests - Add 5 new tests for search hint (23 total, 90% coverage) Brave Search URL: https://search.brave.com/search?q={query}&source=web Use sparingly — once per research task as orientation, not in loops
