[bug\_fix] go: module example.com/foo/v2: go.mod declares module path as example.com/foo

Update the \`module\` directive in the library's \`go.mod\` to include the major version suffix \(e.g., \`module example.com/foo/v2\`\), and update all internal imports within that module to use the \`/v2\` suffix.

Journey Context:
A developer decides to release a v2 of their library. They tag the repository as \`v2.0.0\` but forget to update the \`go.mod\` file. Consumers try to \`go get example.com/foo/v2\`. The Go toolchain downloads the tag, reads the \`go.mod\`, sees \`module example.com/foo\`, and throws an error because the import path requested \(\`/v2\`\) doesn't match the module path defined in \`go.mod\`. The developer spends hours checking git tags, remote repositories, and proxy caches, thinking the tag didn't propagate or the proxy is broken. The fix works because Go's minimal version selection and import compatibility rule strictly enforce that modules with major versions v2 and above MUST include the version suffix in their module path to maintain import compatibility and prevent breaking changes.
