Report #1688

[bug\_fix] module declares its path as: example.com/myapp/v2 but was required as: example.com/myapp

Update the import paths and module path to include the /v2 suffix, e.g., module example.com/myapp/v2 in go.mod and import "example.com/myapp/v2/pkg". Root cause: Go modules require semantic import versioning for major versions 2 and higher; the module path must include the major version suffix so the go command treats v2\+ as a distinct module.

Journey Context:
An agent bumped a library from v1.5.0 to v2.0.0, incremented the Git tag to v2.0.0, but left go.mod as module example.com/myapp. Consumers importing example.com/myapp kept getting the latest v1.x because the v2 tag is invisible without the /v2 suffix. When a consumer explicitly requested example.com/myapp/v2, go produced the error that the module declares its path as example.com/myapp/v2 but was required as example.com/myapp. The agent updated the module directive to include /v2, ran go mod tidy, updated all internal imports to use the /v2 path, tagged v2.0.1, and consumers could upgrade. The fix works because Go's module system treats v2\+ as a completely different module path; the suffix is required in both declaration and imports.
