Currently Windows support is hit or miss, and mostly untested. We should:

• Get all of the existing unit tests passing on Windows
  • This will mostly be done by mocking the platform and associated things like path context everywhere to make them more hermetic.
• Add unit tests that mock a Windows environment for a few core commands (format, analyze, build-examples) that we definitely want to support on Windows
• Get unit tests running on Windows in CI (since not all tests are hermetic)
• Fix things as necessary to get those test passing

That won't guarantee that everything runs on Windows, but it gives us a solid foundation to add formal, tested Windows support to more commands on demand.
