feat(community): add Brave Search web search tool (#3528)
* feat(community): add Brave Search web search tool Add a community web_search provider backed by the official Brave Search API (https://api.search.brave.com/res/v1/web/search). API key is read from the tool config (inline api_key) or the BRAVE_SEARCH_API_KEY env var. Output schema (title/url/content) matches existing search tools. No new dependencies (uses the existing httpx). Also wires up the setup wizard, doctor health check, config example, and EN/ZH docs. * refactor(community): drop redundant [:count] slice in Brave search The Brave API already caps results via the `count` request param, so client-side slicing was redundant. Tests now simulate the API honoring `count` instead of relying on the slice. Addresses PR review nit. * style(tests): apply ruff format to test_doctor.py Collapse multiline write_text calls onto single lines to satisfy the CI ruff formatter (lint-backend was failing on format --check).
