* Fail closed on delegated fetch backends to close SSRF gap
* fix(community): resolve delegated-fetch credentials from one config snapshot
Address review feedback on the fail-closed SSRF guard:
- firecrawl/fastcrw client construction no longer re-reads get_app_config(),
so the API key and endpoint come from the same revision the endpoint screen
validated (prevents cross-revision credential misrouting).
- fix the browserless test double to accept the new two-argument
_get_browserless_client signature.
- document the check-only (DNS rebinding) caveat on
validate_delegated_backend_url.
- add a CHANGELOG upgrade note for the default self-hosted backend break.
* fix(doctor): consolidate delegated fetch backend checks and deployment guidance

* fix(community): normalize max_results before handing it to Firecrawl and fastCRW
* test(community): pin the explicit-null max_results shape
The parametrized `omitted` case reused None as its "key absent" marker, so
`extra["max_results"] = configured` never ran for None and the key-present,
value-null YAML shape never reached _coerce_max_results. Use a distinct
sentinel for absence and add an explicit-null case per provider.

* feat(community): add bounded retries for Jina web fetch
Closes#6116
Keep retries opt-in and share a total deadline across requests and backoff. Preserve cancellation and the existing Error contract. Include offline DNS and local-wheel fixture corrections needed to run the complete backend suite in the isolated verifier.
