RutOS System Integrity Enhancement

| Detailed description
|
With the release of RutOS version {{{RutOS}}}, the device’s critical system files will become read-only by default. This prevents unauthorized or accidental modifications that could damage the system’s integrity. Standard users operating within typical parameters should not be affected, while those who rely on direct file alterations will need to adjust their workflows. Custom firmware options are expected to allow reverting to a more flexible configuration if required.
