Context

GeneralsXZH (Zero Hour expansion) has CI/CD pipeline for Linux via Docker. GeneralsBase (non-expansion) is now playable on Linux.

Goal

Extend CI/CD pipeline to build and test Generals Base alongside GeneralsXZH:

• Docker-based Linux builds
• Automated smoke tests (menu launch, skirmish map load)
• Build logs and artifacts captured
• Same determinism and quality gates as ZH builds

Acceptance Criteria

• GitHub Actions workflow updated to build GeneralsBase variant
• Docker build scripts include Generals Base targets
• CI runs on push to main and PRs
• Build artifacts (ELF binaries) captured
• Smoke tests validate both Generals and GeneralsXZH
• Build times acceptable (< 30 min preferred)
• Documentation updated (.github/workflows/, scripts/README)

Notes

• Reference: .github/workflows/ for ZH pipeline
• Generals Base uses same build system as ZH (CMake presets)
• Only Linux CI initially (may extend to macOS/Windows later)
