Packer-built almalinux9-gobuilder is retiring. Moves test and
pre-commit steps to artifactapi docker-internal/gobuilder 0.1.2-alma9
(estate CA, go1.26.7, go-cache-plugin baked in).
- Repoint both steps at the new image, quoted (has a colon)
- Drop curl/sha256sum bootstrap for go-cache-plugin; it's on PATH now
- Set GOCACHEPROG as a static env var instead of a conditional export
- Verified build/test still pass with unreachable/invalid S3 creds —
best-effort degrade is a plugin runtime property, unaffected
