Extract platform-specific syscall code into proc_unix.go and proc_windows.go with appropriate build tags. This fixes TestCrossPlatformBuild which failed because syscall.SysProcAttr.Setpgid is Unix-only. Changes: - setSysProcAttr(): Sets process group on Unix, no-op on Windows - isProcessAlive(): Uses Signal(0) on Unix, nil signal on Windows - sendTermSignal(): SIGTERM on Unix, Kill() on Windows - sendKillSignal(): SIGKILL on Unix, Kill() on Windows Fixes gt-3078ed Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
