Subject: [PATCH] ci: lint with go vet, pin Go from go.mod

The build was failing on every PR: golangci-lint (latest, built on go1.24)
refuses to lint a module targeting go1.25, and setup-go was pinned to a stale
1.23.0. Switch the lint step to `go vet` (matching the Makefile/AGENTS.md lint
command) and read the Go version from go.mod so it can't drift again. Bump the
deprecated actions/cache@v3 to v4.
