[bug\_fix] go: missing go.sum entry for module example.com/[email protected]

Run \`go mod tidy\` to ensure \`go.sum\` contains the cryptographic hashes for all exact module versions required by the current build, or run \`go get example.com/[email protected]\` to fetch the specific missing dependency.

Journey Context:
A developer pulls the latest changes from their version control system, which includes a newly added import in a \`.go\` file. They run \`go build\` and get a \`missing go.sum entry\` error. They might try \`go build\` again, confused, assuming the build tool automatically fetches and verifies dependencies like npm or pip. However, Go requires explicit verification via \`go.sum\`. The \`go build\` command intentionally refuses to modify \`go.sum\` to prevent untrusted dependencies from silently slipping in. The developer runs \`go mod tidy\`, which calculates the exact required dependencies, fetches them, populates \`go.sum\` with their checksums, and then the build succeeds.
