BUG | GO module `smithy-dafny-standard-library` does not compile with `GOOS=windows`

[j-dubb-dev]

Building the smithy-dafny-standard-library module package fails when GOOS=windows because smithy-dafny-standard-library/Time_/externs.go is using the syscall.Rusage type and calling syscall.Getrusage which doesn't exist in the syscall package for windows builds (https://cs.opensource.google/go/go/+/master:src/syscall/syscall_windows.go)

Steps to reproduce

Create a test directory

mkdir tests
cd ./tests
go mod init test
go get github.com/aws/aws-cryptographic-material-providers-library/releases/go/smithy-dafny-standard-library/Time_

This should produce a go.mod file like this

module test

go 1.25.1

require (
	github.com/aws/aws-cryptographic-material-providers-library/releases/go/smithy-dafny-standard-library v0.2.2 // indirect
	github.com/dafny-lang/DafnyRuntimeGo/v4 v4.10.1 // indirect
)

Then create main.go with the following content

package main

import _ "github.com/aws/aws-cryptographic-material-providers-library/releases/go/smithy-dafny-standard-library/Time_"
func main() {}

Running GOOS=linux go build . and GOOS=darwin go build . compiles without error

Running GOOS=windows go build . yields the following error

>  test GOOS=windows go build .
