chore(release): bump NixOS to 25.11 and update channels

Upgrade the NixOS `stateVersion` from 25.05 to 25.11 in all system configuration files and update all nix channel URLs to the 25.11 releases. Adjust Home Manager and terminal module configurations accordingly, clean up duplicated SSH keys, and update LLaMA server command lines. Minor housekeeping changes to package definitions and other configuration files are also included.
