[bug\_fix] go: 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 codebase.

Journey Context:
A developer checks out a feature branch that added a new third-party dependency. They run \`go build\` and get a 'missing go.sum entry' error. They try \`go get ./...\` but it doesn't update go.sum properly. They might try manually pasting a hash into go.sum, which leads to further checksum errors. The root cause is that go.sum is a lockfile of cryptographic checksums, and it must be updated whenever a new dependency is added. \`go mod tidy\` is the canonical way to add the missing checksums and remove unused ones, ensuring the build is reproducible and secure. It works because it acts as the canonical state synchronizer for module dependencies, whereas manual edits or partial \`go get\` commands can leave the dependency graph in an inconsistent state.
