[bug\_fix] verifying module: checksum mismatch

Remove the problematic module's entry from go.sum \(or delete entire go.sum\) and run \`go mod tidy\` to regenerate the checksum. If using a proxy, clear the local cache with \`go clean -modcache\`.

Journey Context:
After updating a dependency via \`go get -u\`, the developer got a checksum mismatch during build. They suspected a corrupted download or an outdated proxy cache. They checked the hash reported by the error against the one in go.sum. They deleted go.sum and ran \`go mod download\` again, but the error persisted. Finally they cleared the module cache with \`go clean -modcache\` and re-ran \`go mod tidy\`, which fetched fresh checksums from the origin \(not proxy\) and resolved the issue.
