Adopt a documented list of which workers still import wellknown.ts vs. have it hand-rolled inline

The Content-Signal/llms.txt/robots.txt routes were added via 6 parallel dispatched agents touching all 36 sites at the time — some may have received hand-rolled inline versions rather than importing the shared kit. Adopt a definitive list (via grep) so future shared-kit edits know their real blast radius.
