telegram is no longer outbound only (V-637)

The correction gesture now reaches all three surfaces, and CLAUDE.md said
only /chat had it. Doc 23 carries the decisions: long-poll rather than a
webhook, the backlog dropped on start, one accepted sender, and the two-tap
keyboard.

+block says `intake`, it long-polls because the box takes no inbound connections,
+it accepts `chat_id` and no other sender, and it drops whatever queued while the
+daemon was down. It reaches the daemon through `ipc.CoreAPI` alone, so a chat
+turn takes the path `POST /api/chat` takes. Note that the turn source is still
+`tap:text` for both, so provenance cannot tell a chat turn from a typed one.
+Adding a rung to the ladder
 in `runTurn` means adding its name to `preRouteLadder` in
 `cmd/mavend/decisiontrace.go`, or that rung is silently missing from the record.
