Adds one record, MARKET_STATS, to the run's key-value store (Output tab): one sheet per search, computed on the jobs read: total jobs on Foundit, top hiring companies, cities, salary bands (min / median / max), experience asked, top skills, work from home share, company vs consultant, jobs posted on Foundit vs copied from other sites, quick apply share. One sheet per search you typed or pasted (not per part of a split search), no extra request; a search not read because maxItems was reached first has no sheet (set maxItemsPerQuery to read every search). Charged once per sheet (event market-stats, see the pricing); a search with no job gets a sheet of 0 jobs, never charged; unticked (default) = never charged.
