unkin-agent 9e3cef8ef8 ci: switch Go steps to estate gobuilder + S3 build cache (#20) ...

Why: unify on the estate gobuilder image and share the S3-backed Go
build cache across repos instead of pulling golang:1.25 cold each run.

- Swap build/test/pre-commit/release Go steps to gobuilder:0.1.2-alma9
- Add GOCACHEPROG (go-cache-plugin, absolute cache dir) + S3 cache env
- Source AWS creds from org-level GOCACHE secrets
- Leave lint step on golangci-lint image (binary absent from gobuilder)
- Leave rpm/upload/release steps untouched (no Go toolchain)
