Changes build strategy from building on target machines to building
locally and deploying pre-built artifacts. This simplifies target
machine configuration and improves deployment speed.
- Add build-local.nix for local machine-specific builds
- Update krops.nix to deploy built artifacts from ./build/{machine}/dist
- Remove build-helper.nix and build dependencies from machine configs
- Update documentation with new build-then-deploy workflow
- Add .gitignore for build directories
