Each radio's "Messaging in ATAK" section gains a "Direct messages" switch. With it on: - Companions this radio can message (a MeshCore companion whose key it holds, any Meshtastic node) get a chat endpoint on their marker, so ATAK offers to message them. Repeaters, room servers and sensors do not. - A message to a companion's contact goes out from this radio through the Chat send path as a direct message, prefixed [CALLSIGN], and shows in Chat. - A DM heard from a companion goes to the ATAK device that last wrote to it, or to every connected device when none has; it is held (with channel messages, 50 max, 24 h) while the device it is for is away. Retried copies are relayed once. Command replies from repeaters and room servers are not relayed. - A companion with no marker on the map gets a contact at 0, 0 for a day after the last message, under its marker's uid, so a later marker replaces it. - A message ATAK cannot deliver (DMs off for the radio, or not a node this radio can reach) gets a note in its conversation saying why. - DMs and chat endpoints are never sent to the remote TAK server. New IPC: tak:pushDirectMessage and tak:setDirectMessaging. TakInboundChat now carries a target (channel or direct) in place of channelKey.

Reticulum joins MeshCore and Meshtastic for direct messages with ATAK, behind its own switch in a new "Reticulum messaging in ATAK" section. With it on: - An LXMF peer with a position whose delivery destination is known under its own node id gets a chat endpoint on its RN- marker. A peer whose LXMF address belongs to another destination (a telephony or bare identity hash remapped) stays a plain marker, since its replies would come from a different contact. RMAP interfaces stay plain markers. - A peer with no position appears at 0, 0 only once mesh-client has a conversation with it (a DM sent or received, before or since TAK was running), so ATAK's contact list does not fill with every peer heard. The renderer lists up to 64 such peers, most recent first, over the new tak:setDirectPeers IPC; main announces their contacts with the channel contacts and removes one dropped from the list. - A message from ATAK goes out as an LXMF DM through the Chat send path, with its resends; its delivery proof feeds the PR 4 receipt. - A newly stored inbound LXMF message from a peer is relayed to ATAK from ingestReticulumLxmfPayload; status updates, our own sends and reactions are left out.

A direct message sent from ATAK now tells the device that wrote it how it went, once mesh-client's automatic resends settle: - Acknowledged by the companion: a b-t-f-d delivery receipt naming the device's message id, so ATAK marks it delivered. - Still unacknowledged after the last resend (4 tries): a "Not confirmed" note in the conversation, quoting the message. For MeshCore it adds that a flood advert from each radio usually fixes a DM that keeps failing. - Never sent (no radio could take it): a "Not sent to the mesh" note. A note for a device that is away waits with the held messages; a receipt is dropped. Main waits up to 30 minutes for an outcome. The resend controller reports how each send's lineage ends (acked or gave up), keyed by the first send's store id through re-keys and resends, via subscribeAutoResendOutcomes. takDmStatus.ts watches DMs sent from TAK and reports their outcome over the new tak:dmStatus IPC, keyed by a dmRef main attaches to each inbound DM.

The radio TAK uses per protocol is recorded in an effect, so for a moment after a switch to another radio of the same protocol it can still name the old one, whose transport may still be open. findTakSendTargets now drops a direct target whose recorded radio is not the protocol's current identity.

Failed direct sends reach the originating client: valid for this PR on its own, and handled in the next PR of the stack, Colorado-Mesh#1283 (delivery receipts). There, main attaches a dmRef to each direct message. When relayTakChatToMesh fails to send, or finds no radio that can send, it reports not-sent over the new tak:dmStatus IPC. TakServerManager.reportDmOutcome then writes "mesh-client: Not sent to the mesh: …" into that conversation, on the device that wrote, holding it if that device is away. The same channel carries "delivered" and "Not confirmed", so I've kept it in Colorado-Mesh#1283 rather than add a separate IPC here. Stale protocol radio: valid, and fixed in this PR. findTakSendTargets now drops a direct target whose recorded radio isn't the protocol's current identity (getIdentityIdForProtocol, the resolver App uses). A test covers the switch window.

Merge main into feat/tak-dm-receipts after Colorado-Mesh#1282 merged branch, so this merge keeps the branch's files as they are (-s ours). The PR diff now shows only the delivery receipt changes.

directContactsentry can admit a stale Reticulum target.findTakSendTargetsreturns its node ID without a Reticulum-specific target guard. When that ID resolves to another LXMF destination,sendReticulumChatMessageaccepts the replacement hash and can send the message to the wrong recipient.A node with no destination does not transmit.

A peer ATAK may still message, from an earlier direct message or as a conversation peer, can have its LXMF address remap to another destination after it was listed. findTakSendTargets now applies the same own-destination rule used for chat endpoints and drops the target, so the message never goes to a different destination whose replies would arrive under another contact.

Fifth and last of the TAK messaging PRs. Builds on #1283 (which builds on #1282 and #1280), so until those merge this PR also shows their commits; review the top commit only.
What it does
Reticulum joins MeshCore and Meshtastic for direct messages with ATAK. It has its own Reticulum messaging in ATAK section in the TAK panel, holding only a Direct messages switch (off by default), since Reticulum has no channels to serve. With it on:
RN-marker, so ATAK can message it.tak:setDirectPeersIPC.ingestReticulumLxmfPayloadhands each newly stored inbound LXMF message on to ATAK. Status updates, our own sends and reactions are left out. As with the other radios, a reply goes to the device that last wrote, or to every device when none has.Changes
