fix: answer the search gate's missed queries

terms weighs 20, so the version table outranks MAME parts. The FAQ carries ios, iphone, ipad, the file page check my dump, and a console's regional lead names it (the PlayStation BIOS). The FAQ quotes the bootstrap's fingerprint message again. The troubleshooting page, which answers the dc/ trap, joins the pages that answer dc bios missing. The gate starts node without its compile cache.
