[bug\_fix] go: github.com/user/[email protected]...: invalid pseudo-version: does not match version-control tag

Use go get github.com/user/repo@latest or specify the exact semantic version tag \(e.g., go get github.com/user/[email protected]\) instead of referencing a commit hash or branch name directly.

Journey Context:
A developer tries to update a dependency by running go get github.com/user/repo@master or go get github.com/user/repo@abc123. The Go toolchain resolves this to a pseudo-version based on the commit timestamp. Later, the upstream repository releases a proper semantic version tag \(e.g., v1.0.0\), but the developer's go.mod is stuck on the pseudo-version. When another developer clones the repo, go mod tidy fails because the pseudo-version resolution fails or conflicts with the new semantic version. The fix is to explicitly request the semantic version tag, which is the canonical way Go modules are versioned, ensuring deterministic builds and avoiding pseudo-version resolution errors.
