Peers publish busy intervals per actor (iCal free/busy model — privacy-
preserving, not event details). ev/peer-with-busy, ev/peer-busy;
ev/federated-busy unions local availability-db busy + trusted peers' published
busy (sorted); ev/federated-free? answers cross-instance availability,
half-open, trust-gated (untrusted peers ignored). 219/219 green.
