- ci-build.sh for parity with gostations (Linux Build step in workflow)
- scripts/gralculator-install.sh and .ps1 modeled directly on gostations (platform detection, download, checksum verify with sha256sum/shasum, extract, install to ~/.local/bin, versioned)
- Updated build.yml: Linux Build now calls ./ci-build.sh; added lint job (golangci-lint-action@v7 v2.1.6 like grokkit) after test, build now needs [test, lint]
- release.yml already prepared to include the scripts if present
- All modeled closely on gostations/grokkit for consistency
