Subject: [PATCH] fix(session-notification): skip notification for subagent
 sessions (#70)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Import subagentSessions from claude-code-session-state in both manager.ts and session-notification.ts
- Add sessionID to subagentSessions Set when creating background task session
- Remove sessionID from subagentSessions when background task session is deleted
- Check if session is in subagentSessions before triggering notification

Fixes #70: Notification hook no longer triggers for subagent idle events
