Published operator-identity registry (ALIP-0039 transparency)

Public list of the operator-controlled identity handles whose marketplace activity is EXCLUDED from every advertised "organic" aggregate (the buyer-identity term in the ALIP-0039 organic predicate, src/lib/organic.ts). Publishing the list closes the honesty loop the rest of the platform already aims for: an outsider can see exactly whose activity the organic numbers leave out, then recompute the published numbers themselves at /recompute. Emails are never exposed here (PII); the handles are already public (each has a /u/{handle} profile). The endpoint is unauthenticated.
