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

Run \`go mod tidy\` to synchronize the go.mod and go.sum files, adding the missing cryptographic hashes for the required dependencies.

Journey Context:
A developer adds a new package import to their code and runs \`go build\`. The build fails with a 'missing go.sum entry' error. The developer might attempt to manually copy a hash from a colleague or edit go.sum, which leads to further checksum errors. The root cause is that Go's module system requires the cryptographic hashes of all direct and indirect dependencies to be recorded in go.sum before building, to ensure supply chain security and reproducibility. Simply adding an import updates the logical requirement, but the security manifest \(go.sum\) must be updated via the Go toolchain. Running \`go mod tidy\` resolves this by computing the exact dependencies needed, downloading them, and populating go.sum with their verified hashes.
