Add Windows-compatible SDK tests

Todo: add Windows-compatible SDK tests mirroring the semantics of the existing Linux tests (cmd.exe commands, Windows paths, documented Windows session limitations), runnable against a Windows sandbox.

Hi! I’d like to work on this.

I’m planning to start with a focused PR for the TypeScript SDK first, adding a Windows-specific E2E test file that mirrors the existing Linux E2E coverage where possible.

The test would use the windows snapshot, Windows-style paths from getWorkDir(), and cmd.exe commands for process execution. I’ll keep Linux-specific shell/session behavior separate or documented where it does not translate directly to Windows.

If this scope looks good, I can use the same pattern for the other SDKs afterward.
