[bug\_fix] go: module ... requires [email protected] \(Z >= 1\): go.mod has post-v0 module path .../vN

Update the import paths in the source code to include the major version suffix \(e.g., /v2\), and update the require directive in go.mod to match, or downgrade the dependency to a v0/v1 version if the major version bump wasn't intended.

Journey Context:
A developer adds a new dependency example.com/bar at version v2.0.0 using go get example.com/[email protected]. The build fails with a 'post-v0 module path' error. They are confused because they explicitly requested v2.0.0. They inspect the go.mod of the dependency and see 'module example.com/bar/v2'. The Go module system enforces Semantic Import Versioning: if a module's path lacks a /vN suffix but its version is v2.0.0\+, Go rejects it as a malformed module. Conversely, if the go.mod says /v2, the importing code must import it as example.com/bar/v2. The developer updates all their import statements to include the /v2 suffix, runs go mod tidy, and the build succeeds.
