* Add Brave image search community tool
* fix(community): length-cap Brave web_search queries
Apply _clean_query in web_search_tool so over-long queries are trimmed
to Brave's 400-char limit before the API call, matching image_search_tool
and avoiding HTTP 422 from the Brave Search API.
* fix(community): harden Brave image search SSRF guard and dimension mapping
Address PR review findings:
- Catch ValueError from urlparse so a malformed bracketed-IPv6 URL skips
one item instead of crashing the whole image_search call
- Reject IPv6 literals embedding a non-global IPv4 (IPv4-mapped, 6to4,
NAT64, IPv4-compatible), closing the loopback/private SSRF bypass
- Report width/height from the dict of the URL actually returned, so a
surviving thumbnail no longer reports the dropped original's dimensions

* 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).
