Subject: [PATCH] fix(playground): Run mengonsumsi stdinQueue atomik via
 consumeStdin()

- runActiveFile() memanggil consumeStdin() (antrean + draft, digabung, dikosongkan)
- pesan info jika stdin kosong: program yang membaca input akan mendapat EOF
- hapus pembacaan consoleInput langsung yang menyebabkan baris hilang
