[bug\_fix] go: github.com/user/[email protected]: go.mod has non-... module path "github.com/user/original"

Use a \`replace\` directive with a local path pointing to the cloned fork, or update the fork's \`go.mod\` module path and all its internal imports to match the new fork URL.

Journey Context:
A developer tries to use a forked library by running \`go get github.com/user/fork\`. The command fails, stating the \`go.mod\` has a non-matching module path. The developer is confused because the fork is just a copy of the original. They learn that Go strictly enforces that the \`module\` directive in \`go.mod\` must match the repository path from which it was fetched. To use the fork without rewriting all internal imports in the forked repository, the developer must clone the fork locally, keep its \`go.mod\` as \`module github.com/user/original\`, and use a local replace directive in their project: \`replace github.com/user/original => ../local/fork\`. This works because local replace directives bypass the strict fetch-path matching, allowing the original module path to coexist with the local file source.
