Batch URL Index Inspection

Inspects the Google index status of MANY URLs in one call: a batch wrapper over gsc_url_inspect for site-wide crawl-freshness audits (which URLs Google recrawled since a content change, which are indexed, which were never crawled). Returns a compact row per URL — page_url, verdict, coverage (coverageState), last_crawl, indexing, google_canonical — deliberately WITHOUT the rich-results / mobile detail so the whole table stays within the result-size limit. page_urls is a list of full URLs (a comma/newline-separated string is also accepted). `limit` = URLs per call (0 = all given URLs). Google's URL Inspection API is quota-limited (~2000/day and 600/min per property) and answers ~6.6 s per URL; URLs are inspected 5 at a time within a 100-second budget, URLs beyond it come back in `skipped`, and if a quota or rate error is hit mid-batch the tool STOPS and reports how many rows it managed. site_url must be a verified property. To ask Google to crawl the URLs that come back unknown, discovered-not-indexed or stale, pass them to gsc_request_indexing.
