[bug\_fix] missing go.sum entry for module providing package ...

Run go mod tidy to add the missing entries to go.sum, then commit the updated go.mod and go.sum files to version control. The Go toolchain requires exact cryptographic hashes of downloaded modules in go.sum to ensure reproducibility and security.

Journey Context:
A developer adds a new import to their code, writes the feature, and pushes a PR. The CI pipeline fails with missing go.sum entry. The developer is confused because the code compiles locally. They realize their local IDE or go run automatically added the dependency to go.mod and go.sum, but they forgot to commit both files, or they only committed go.mod. The Go toolchain requires exact cryptographic hashes of downloaded modules in go.sum to ensure reproducibility and security. The fix is simply to run go mod tidy and ensure both go.mod and go.sum are staged and committed together.
