[bug\_fix] go: [email protected]: invalid version: module path ... must have major version suffix /v2

Append the major version suffix \(e.g., \`/v2\`\) to the \`module\` directive in the dependency's \`go.mod\`, and update all import paths in the consuming code to include the suffix.

Journey Context:
A developer attempts to upgrade a dependency to its new major version using \`go get github.com/example/[email protected]\`. The command fails, complaining about a missing major version suffix. The developer is frustrated because the Git tag \`v2.0.0\` clearly exists. They investigate and find that Go's Semantic Import Versioning rule requires the module path to reflect the major version if it is v2 or higher. The fix is to change the import statements in the code from \`github.com/example/pkg\` to \`github.com/example/pkg/v2\`. This works because Go treats different major versions as entirely distinct modules, and the path suffix enforces this separation, preventing v1 and v2 from being linked together accidentally in the same build.
