Subject: [PATCH] ci: switch Go steps to estate gobuilder + S3 build cache

Moves build/test/pre-commit/release Go steps off golang:1.25 and the
old almalinux9-gobuilder onto the verified gobuilder:0.1.2-alma9
image, and wires GOCACHEPROG (go-cache-plugin) at an absolute cache
dir to the shared S3-backed Go cache. Leaves the golangci-lint step
on its dedicated image (gobuilder has no golangci-lint binary) and
leaves the rpm/upload/release steps untouched (no Go toolchain).
