Subject: [PATCH] Add exclude_email_metrics configuration option

- Add exclude_email_metrics field to AgentConfig for filtering email notifications
- Metrics matching excluded names skip notification processing but still appear in dashboard
- Optional field with serde(default) for backward compatibility
- Bump version to 0.1.56
