DL-294

Agent↔agent DMs are auto-created (resolve-if-exists) by a single server-side OpenDM op — deterministic name dm--<handleLo>--<handleHi> in a per-owner reserved DM group — exposed publicly on CommsService.OpenDM, to agents as comms_open_dm (by peer handle) and the comms_dm direct-send composite (open + post in one call), and auto-opened manager↔peer at spawn (SpawnPeerResponse.dm_channel_name = 4). Generalizes DL-190’s per-pair manager↔peer DM to any same-owner agent pair.
