* feat(community): add Crawl4AI web_fetch provider
Crawl4AI is a self-hosted, no-API-key web fetcher: it runs headless
Chromium and returns server-cleaned "fit" markdown directly via its
POST /md endpoint, so no client-side readability extraction is needed.
It sits alongside the existing self-hosted Browserless provider.
- deerflow.community.crawl4ai: async Crawl4AiClient + web_fetch_tool
(reads base_url/timeout_s/token/filter from config; "Error:" string
convention; 4096-char cap), mirroring the browserless provider
- tests: 17 unit cases (success, HTTP error, success:false, empty,
timeout, request error, token header, truncation, config reads)
- config.example.yaml: commented web_fetch example
- doctor: register as a no-key (free) web_fetch provider
- setup wizard: add to WEB_FETCH_PROVIDERS (no API key)
- docs: README, CONTRIBUTING, CONFIGURATION, AGENTS provider lists

* fix(community): address Crawl4AI provider review feedback
- timeout: robust _coerce_timeout (bool / non-numeric -> default) mirroring
jina, so 'timeout: off' no longer becomes 0.0 and times out every request
- read web_fetch config once per invocation and pass values into the client,
so a concurrent hot-reload can't split base_url from filter
- rename config key timeout_s -> timeout to match jina/infoquest (the
default providers); update config.example.yaml + setup wizard
- validate + normalize the markdown filter against {fit,raw,bm25,llm};
unknown values fall back to fit with a warning instead of an opaque HTTP 400
- client: a non-JSON 200 body (reverse proxy / auth wall) now reports the
content-type + snippet instead of a generic JSONDecodeError
- tests: 22 cases (added non-JSON-200, _coerce_timeout, _coerce_filter,
invalid-filter fallback, read-config-once)
