fix(cli): v0.5.2 — poll-based push delivery (1s interval)

Replace WS onPush→notification with timer-based buffer drain.
The old claude-intercom used 1s polling and worked reliably.
WS async callbacks may not flush stdio properly for MCP
notifications. Polling on a timer ensures consistent delivery.
