Any directives in required dependency modules are ignored.
It is an error to list a `godebug` with an unrecognized setting.
(Toolchains older than Go 1.23 reject all `godebug` lines, since they do not
understand `godebug` at all.) When a workspace is in use, `godebug`
directives in `go.mod` files are ignored, and `go.work` will be consulted
for `godebug` directives instead.
