Follow-up on the salvaged #49830 hardening. The contributor's sensitive query-param set included bare English words (code, key, auth, session, sig) that double as ordinary page facets — ?code= on promo/challenge pages, ?key= as a search facet, ?session= on blogs — so web_extract and cloud browser_navigate would refuse a large slice of normal browsing. Narrow the set to unambiguously credential-named params (access_token, authorization, client_secret, password, token, x-amz-signature, ...). Prefix-based vendor-key redaction (is_safe_url) still catches recognizable key shapes; this set is the belt-and-suspenders for opaque secrets carried under an explicit credential-named parameter. Also fixes two intra-PR-staleness test breakages surfaced by salvaging onto current main: - web_extract_tool() no longer accepts use_llm_processing= (signature changed since the PR was authored) — dropped the invalid kwarg. - agent.redact now fully masks keyed 'token=<secret>' to 'token=***' instead of partial 'sk-...'; the console-redaction test now asserts the real invariant (secret body gone) rather than the exact mask format. Added a regression test that generic English-word query params are NOT blocked by the credential guard.
