[bug\_fix] go: inconsistent vendoring: /path/to/project/vendor/modules.txt: module 'github.com/example/lib' is required but not in vendor directory

Run \`go mod vendor\` to regenerate the vendor directory. If that fails, delete the vendor directory and run \`go mod vendor\` again. Ensure all dependencies are declared in go.mod. If using a fork or replace directive, verify the replace path is correct.

Journey Context:
A developer cloned a project that had a vendor directory committed to git. After switching branches and running \`go build\`, they got 'inconsistent vendoring'. The developer tried manually copying files into vendor but it didn't work. The root cause was that the vendor directory was stale — it didn't match the go.mod and go.sum after a dependency update. The fix was to delete the vendor folder and regenerate it with \`go mod vendor\`. This error is common when team members update go.mod directly without running \`go mod vendor\` afterward, or when using version control branches that change dependencies.
