- Remove deployment.json file generation from outputs.nix
- Add throw for deprecated deployment.file usage with upgrade instructions
- Remove vars data from deployment.data
- Update Machine class to use direct select() calls instead of deployment property
- Update all deployment property accesses to use direct selectors
- Add precaching for frequently accessed values in update.py:
- Module paths for facts and vars
- Deployment settings (requireExplicitUpdate, nixosMobileWorkaround)
- Services and generators data
- Secret upload locations
- This removes unnecessary JSON serialization and makes the code more composable
