Enable Restart=on-failure with a 5-second delay. Implement a safety limit: stop restarting if the service fails more than 5 times within 1 minute. Prevent infinite crash loops and resource exhaustion.

TL;DR
Enable Restart=on-failure with a 5-second delay.
Implement a safety limit: stop restarting if the service fails more than 5 times within 1 minute.
Prevent infinite crash loops and resource exhaustion.
Reason for add this
The Raspberry Pi's I2C connection uses DuPont jumper wires, which are prone to intermittent loose connections. This causes momentary signal loss and triggers service crashes. To improve system resilience, I implemented a systemd auto-restart policy to handle these transient failures, while including a failure threshold to prevent infinite restart loops in the event of a permanent hardware failure.
This is a compromise to avoid soldering the jumper wires between the LCD2004 and the Raspberry Pi. Additionally, implementing an auto-restart feature is a beneficial improvement for overall system resilience.
