feat: add dnclient for defined.net managed Nebula VPN - #707
Merged
Conversation
Packages the dnclient v0.9.6 static binary as a custom derivation, overlays it into pkgs, and adds a NixOS service module behind an opt-in genebean.services.dnclient.enable flag. Enables it on nixnuc. Enrollment is done manually once with `sudo dnclient enroll -code <CODE>`; dnclient handles cert rotation automatically after that.

Enrollment is a one-time manual step per host:
sudo dnclient enroll -code <CODE>(get the code from the defined.net dashboard). After that, dnclient handles cert rotation automatically via the defined.net API.🤖 Generated with Claude Code
