[bug\_fix] go: github.com/foo/[email protected]: reading github.com/foo/bar/go.mod at revision v1.0.0: unknown revision v1.0.0

Run \`GOPROXY=direct go mod tidy\` to bypass the Go module proxy cache and fetch directly from the source repository, or wait for the proxy cache to expire.

Journey Context:
A developer is trying to pull a dependency that a colleague just published. They run \`go get github.com/foo/[email protected]\` but get an unknown revision error. They check the repository in the browser and the tag \`v1.0.0\` clearly exists. The issue is that the default Go module proxy \(\`proxy.golang.org\`\) has not yet fetched the new module, or it has cached a 404 Not Found response from when the tag didn't exist previously. The Go toolchain queries the proxy, which returns the stale cached error. The fix is to temporarily bypass the proxy by setting the \`GOPROXY=direct\` environment variable, forcing the toolchain to fetch directly from the VCS \(e.g., GitHub\). This reveals the tag exists and allows the build to proceed.
