[bug\_fix] go: module github.com/A requires github.com/[email protected] but github.com/[email protected] is required

Remove or update the replace directive in go.mod that is forcing the dependency to an older version, or update the module requiring the older version.

Journey Context:
A developer runs go mod tidy and gets a version conflict error. They are confused because they didn't specify a version for github.com/C. They look at the go.mod file and find a replace github.com/C => github.com/C v1.0.0 directive left over from a previous debugging session or added by another developer to fix a different bug. Because the main module strictly requires v1.0.0 via the replace directive, but github.com/A requires v1.2.0, Go's Minimal Version Selection \(MVS\) cannot resolve the graph. The fix is to remove the replace directive and let MVS naturally select v1.2.0 to satisfy all requirements. This works because replace directives in the main module override MVS for the entire dependency graph, forcing a specific version that might be incompatible with other dependencies.
