Feature request: hide the Windows console window for ConPTY child processes

[JuReyms]

Problem

Applications that use node-pty in the background on Windows may briefly show a console window for every spawned ConPTY process. This is disruptive for batch-style CLI invocations where the host application already owns the UI.

Current API

IPtyForkOptions exposes useConpty, but no option analogous to Node's windowsHide.

Requested API

Please consider an explicit, opt-in option such as:

pty.spawn(file, args, {
  useConpty: true,
  windowsHide: true,
});

On Windows, it should prevent a visible console window while preserving the actual pseudo-terminal and its output. Other platforms should retain current behavior.

Why this matters

Switching from a PTY to ordinary pipes is not an acceptable workaround for tools that require a real console: some CLIs can exit successfully yet provide no capturable output when run through pipes.

Acceptance criteria

• No visible terminal flash when windowsHide is enabled on Windows.
• ConPTY input/output, resize, exit code, timeout, and cancellation behavior remain intact.
• Unsupported platforms retain current behavior or ignore the option safely.

Happy to test a Windows implementation.
