Introduce two new configuration directives to protect disks from overheating:
- temp_limit <TEMPERATURE_CELSIUS>
Sets the maximum allowed disk temperature. When any disk exceeds this limit,
SnapRAID stops all operations and spins down the disks.
- temp_sleep <TIME_IN_MINUTES>
Specifies how long disks remain in standby after a temperature event.
Defaults to 15 minutes.
These options allow SnapRAID to automatically pause activity and cool down
disks when a temperature threshold is reached, improving data safety and
hardware longevity.
