 This package provides a monitoring node that detects ROS 2 node crashes by analyzing `launch.log` files, rather than subscribing to `/rosout` logs.

 ## Overview

+- **Node name**: `autoware_process_alive_monitor`
 - **Monitored file**: `launch.log`
 - **Detected event**: Looks for lines containing the substring `"process has died"` and extracts the node name and exit code.
