Breaks out wild-setup phases into independently-runnable scripts.
Remove deprecated scripts and add Talos schema mappings - Deleted the following scripts as they are no longer needed: - create-installer-image.sh - detect-node-hardware.sh - generate-machine-configs.sh - Added a new file `talos-schemas.yaml` to maintain mappings of Talos versions to their corresponding schematic IDs for wild-cloud deployments. - Updated the README in the home scaffold to simplify the initial setup instructions.
