feat(cli): v0.5.1 — message modes (push/inbox/off)

--inbox: count-only notifications, no content in context
--no-messages: tools only, zero prompt injection risk
Default: push (real-time, current behavior)

Wizard shows mode picker when no flag provided.
MCP instructions tell Claude its current mode.
