Alejandro Gutiérrez 9075ae05df fix(cli): messages stop landing on the wrong sessions (wrong-peer noise, bug9) ...

A reply routinely fanned out to every session of the sender's member,
which is the "peers spread messages to the wrong peers" noise. Three
links fed each other:

- channel meta put the MEMBER key in from_pubkey/from_id, and the skill
  told the model to reply by from_name (repeatable across sessions).
  from_pubkey/from_id are now the sender's session key; the member key
  moves to from_member_pubkey; the skill says reply to from_pubkey.
- a DM to a member key was claimed by that member's daemon socket and
  shown to all its sessions. New daemon/resolve-target.ts is the single
  resolver for /v1/send: a member key maps to its only live session, is
  refused (409 member_target_ambiguous + candidates) when it has several,
  and needs --fanout to reach all of them on purpose. A duplicated
  display name or prefix is ambiguous instead of first-match; control-
  plane rows are never addressable.
- a session MCP whose token didn't resolve fell into the unfiltered SSE
  stream and rendered every sibling's DMs. The MCP now subscribes with
  scope=session and gets no message events without a resolved session.

Also: --self lists only the current mesh and requires a registered
session (it could message its own new row); a DM to a control-plane row
says so instead of the wrong "session pubkeys are ephemeral" hint, and
`peer list --all` tags those rows (bug9).
