[bug\_fix] go: module path must end with /v2 for major version 2 or higher

Append \`/vN\` to the module path in \`go.mod\` and all internal imports for major versions 2 and above, and update consumers to import the \`/vN\` path.

Journey Context:
A developer releases version 2.0.0 of their library by simply creating a \`v2.0.0\` git tag. When consumers try to \`go get\` the new version, Go fails, complaining about the module path not ending in \`/v2\`. The developer might be confused because semantic versioning allows major versions, but Go's semantic import versioning rule requires the module path itself to reflect the major version to prevent ambiguity. The fix requires updating the \`module\` directive in \`go.mod\` to include the \`/v2\` suffix, updating all internal imports within that module to use the \`/v2\` suffix, and then consumers must import it as \`github.com/example/mylib/v2\`. This works because it allows v1 and v2 to coexist in the same build without ambiguity.
