[8h]Implement notification when algorithm shutdown

この issue には説明がありません。

The issue title mentions implementing a notification for algorithm shutdown but provides no details. First, examine the codebase for existing notification systems and algorithm management modules. Look for where algorithms are started and stopped, and identify how notifications are currently sent (e.g., email, websocket, log). Determine the desired notification format and recipients. A good starting point is to search for 'algorithm' and 'shutdown' in the source code to understand the context.
