[bug\_fix] verifying go.sum: missing or corrupted entries

Run go mod tidy to recalculate and append the correct checksums to go.sum, or delete the go.sum file and run go mod tidy to regenerate it completely.

Journey Context:
A developer pulls the latest code from their team's repository after a messy merge conflict. Upon running go build, the toolchain fails with a checksum verification error. The developer tries manually editing go.sum to remove the offending lines, but this leads to further 'missing' or 'corrupted' errors. They eventually realize that go.sum is a strictly verified file and manual edits are error-prone. They run go mod tidy, which resolves the dependency graph, downloads missing modules, and correctly populates go.sum with verified checksums from the Go checksum database, fixing the build.
