[Release] Hwid Grabbing/Logger

This function retrieves the serial number of the motherboard, the primary hard drive, and the network adapter, as well as the CPU ID and the system BIOS version. It then concatenates these values into a single string and hashes it using SHA256 for security. The resulting hashed string can be used as the Hwid value.
