[bug\_fix] go: github.com/foo/bar/v2: module declares its path as: github.com/foo/bar but was required as: github.com/foo/bar/v2

Update the go.mod module directive to include the major version suffix \(module github.com/foo/bar/v2\) and update every internal import in the module to use the /v2 path. Do not just change the consumer's import or delete go.sum.

Journey Context:
An agent imports github.com/foo/bar/v2 because the latest release tag is v2.3.1. go build immediately fails, claiming the module declares itself as github.com/foo/bar. The agent tries go mod tidy, deletes go.sum, switches GOPROXY, and even vendors the dependency, but the error persists. After cloning the upstream repo they see go.mod says module github.com/foo/bar. Root cause: Go modules enforce semantic import versioning, so any module at major version 2 or higher must embed the major version in its module path. The only fix is to change the module declaration and all internal imports to match.
