Michael Bolin 27ace641fe Replace the npm wrapper with the native binary using execve (#57513) ...

## Why

Replacing the Node process lets the native binary receive signals and report its termination directly.

## What changed

- Use `process.execve` on non-Windows platforms when available, preserving CLI arguments and the prepared environment.
- Install a `SIGXFSZ` handler before replacement so the native binary gets the default signal disposition instead of inheriting Node's ignored signal.
- Retain asynchronous spawning for Windows and older Node versions.

## Testing

Extend the exit-status test to check that `execve` leaves no child process and that `SIGHUP` and `SIGXFSZ` terminate it with the original signal, while retaining coverage for the spawn fallback.
