fix: settle the round 4 site merge

Root pages nothing produced are swept, so a table moved to a platform page no longer keeps the address its redirect needs. Data tree pages name their readers, board crumbs end on the Arcade page once, fba2012 is headed FB Alpha 2012, test profiles get no page, and the installer glance lists --declared-only and --offline. sitesources.py goes through run_cli.
