- Fixed YAML syntax and Python version parsing in CNPG operator tasks.
- Added automated detection of active network interface (eth0 vs wlan0) for Retropie and Pi nodes to ensure correct K3s configuration.
- Implemented persistent node taints for retropie.prole.org to exclude CloudNative-PG workloads.
- Added a rollout restart mechanism for cnpg-controller-manager to recover from scheduling on tainted or unstable nodes.
- Removed redundant kubectl-cnpg dependency from the Python installer as it is now managed by Ansible.
- Improved prole.sh to force color output for Ansible playbooks.
- Updated prole.cfg with active K3s token and CNPG version information.
