Replaces stub start/stop methods with working SSE consumer that connects to
claude-mem worker's /stream endpoint, parses new_observation events, and
forwards formatted messages to configured OpenClaw channels (Telegram, Discord,
Signal, Slack, WhatsApp, Line). Includes reconnection with exponential backoff
(1s-30s), connection state tracking, and on/off command toggle. Added 17 tests
covering unit and SSE integration scenarios.
