The go.work file enables workspace mode, which only allows -mod=readonly
or -mod=vendor. -mod=mod fails the build with:
go: -mod may only be set to readonly or vendor when in workspace mode
Drop the GOFLAGS line and let workspace mode pick the default
(readonly). Update go.work.sum to track module checksums.
