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

Run \`go mod tidy\` to synchronize the go.mod and go.sum files with the actual imports in the source code.

Journey Context:
A developer adds a new import to their code and runs \`go build\`. The build fails, stating there is a missing go.sum entry. The developer might try manually editing go.sum, which doesn't work, or running \`go build ./...\` hoping it resolves itself. The root cause is that the go.mod and go.sum files are out of sync with the source code's import statements. The go.sum file stores the cryptographic hashes of the dependencies, and Go refuses to build without verifying them. \`go mod tidy\` analyzes the entire source tree, adds missing dependencies to go.mod, and computes and adds the required checksums to go.sum, making the build safe and reproducible.
