fix: Split go test command for Windows compatibility

- Separate Unix and Windows test commands in workflows
- Remove -coverprofile flag from Windows PowerShell commands
- Fixes parsing error: "no required module provides package .out"

Windows PowerShell was incorrectly parsing the -coverprofile=coverage.out
argument, treating ".out" as a package name. This splits the test
commands by platform to avoid the issue.
