Contributions summary:Hadrien implemented kernel network configuration, including setting up server channels and handling port selection within the Polynote kernel. They refactored the code to move kernel network settings into a dedicated `Kernel` configuration object within `PolynoteConfig`. Further, they made the kernel network settings optional, allowing the system to determine network settings. This work appears to be focused on improving the network configuration and deployment of the Polynote kernel.
