# Smoke-test scripts/install.sh on Linux + macOS against the latest published
# release. The script is the public install path served at get.gortex.dev, so
# any change must prove it still produces a working `gortex` binary. Coverage:
# Linux x64 (ubuntu-latest) and macOS arm64 (macos-14). Intel macOS is not
# tested here — GitHub retired its Intel (macos-13) runners, and install.sh is
# arch-agnostic (only the downloaded artifact differs). Linux arm64 is
# exercised in the release flow.
