check_links
Check one web page for broken links and redirect chains
Fetch ONE public web page and check up to 200 of its links and assets: broken links (4xx/5xx, hosts that don't exist, connection errors, timeouts), redirect chains hop by hop (long chains, loops, https-to-http downgrades), mixed content and links that may just block bots (401/403/429, flagged maybe_bot_blocked). Not a crawler: other pages are not visited. Private/loopback/metadata targets are refused, including names that resolve to them. Takes up to about 45 seconds. Returns counts plus up to 25 problem links. Read-only. Same engine and limits as GET /api/check.
