feat(cli): 1.34.7 → 1.34.13 — multi-session correctness train

Seven-ship sequence that took the daemon from "works for one session"
to "internally consistent for N sessions on one daemon." Architecture
invariant after 1.34.13: every shared store / channel scopes by
recipient (SSE demux at bind layer + token forwarding, inbox per-
recipient columns, outbox sender-session routing).

- 1.34.7  inbox flush + delete commands
- 1.34.8  seen_at column + TTL prune + first echo guard
- 1.34.9  broader echo guard + system-event polish + staleness warning
- 1.34.10 per-session SSE demux (SseFilterOptions) + universal daemon
          (--mesh / --name deprecated) + daemon_started version stamp
- 1.34.11 inbox per-recipient column (storage half of 1.34.10)
- 1.34.12 daemon up detaches by default (logs to ~/.claudemesh/daemon/
          daemon.log; service units explicitly pass --foreground)
- 1.34.13 MCP forwards session token on /v1/events — the actual fix
          that activates 1.34.10's demux. Without this header the
          daemon's session resolved null, filter was empty, every MCP
          received the unfiltered global stream.

Roadmap entry at docs/roadmap.md captures the timeline + the four
known gaps tracked for follow-ups (launch env-var leak, broker
listPeers mesh-filter, kick on control-plane no-op, session caps as
first-class concept).
