[bug\_fix] go: inconsistent vendoring in /project: consider removing vendor directory or running go mod vendor

Delete the vendor directory and run \`go mod vendor\` again, or add \`-mod=mod\` to the go command. Root cause: The vendor directory contains modules that do not match go.mod or go.sum, often after a version bump or merge conflict in go.mod without regenerating vendor.

Journey Context:
After merging a feature branch that updated a dependency, the build started failing with 'inconsistent vendoring'. I tried \`go mod tidy\` but it didn't help. The issue was that the vendor directory still had the old version of the dependency. Running \`rm -rf vendor && go mod vendor\` regenerated the vendor directory to match the updated go.mod and go.sum. This is a common pitfall in monorepos where developers forget to run \`go mod vendor\` after changing dependencies. The environment was a legacy Go 1.16 project that still used vendoring for deterministic builds.

environment: Go 1.16, Linux, monorepo with vendored dependencies, Jenkins CI · tags: vendoring inconsistent go mod vendor directory merge conflict · source: swarm · provenance: https://go.dev/ref/mod\#vendoring
