fam-melcher/kairos-configs ? reverse-engineered prompt

Help me build out this repo for declarative Kairos cluster configuration for my homelab. I want a clean setup where every node is defined from shared base config, a role config, and a per node override, with the files merged in the right order. Please make the repository easy to bootstrap on a new workstation, add a new node from a template, and build the installer ISO that includes the cluster key, treating that image as sensitive. Keep secrets encrypted with SOPS and age, and make sure there are no plain text secrets anywhere. I also want the scripts and docs to be clear enough that I can reinstall or repair a node just from this repository and one private key. If anything is unclear, look up the current Kairos docs online and fill in sensible defaults.
