The gpu package requires C++ headers that only exist locally. Using 'cgo' build tag caused CI failures when CGO was enabled but headers weren't present. Now uses 'luxgpu' custom build tag: - Default: stub implementation (no dependencies) - With -tags luxgpu: full CGO acceleration Build locally with GPU: go build -tags luxgpu ./...
