termux-microphone-record should exit 1 if recording is already in progress or the file already exists

Problem description

termux-microphone-record currently exits 0 even when:

1. Recording already in progress!
2. The file specified with -f already exists (File: fileb already exists! Please specify a different filename)

This makes &&, ||, and checking $? unusable.

Steps to reproduce

.../0/TODO_audio_files $ termux-microphone-record -f fileb
Recording started: /storage/emulated/0/TODO_audio_files/fileb
Max Duration: 15:00
.../0/TODO_audio_files $ termux-microphone-record -f fileb

File: fileb already exists! Please specify a different filename
.../0/TODO_audio_files $ echo $?
0
.../0/TODO_audio_files $ termux-microphone-record -f filec

Recording already in progress!
.../0/TODO_audio_files $ echo $?
0

Expected behavior

exit 1 for the mentioned situations

Start with the termux-microphone-record command and reproduce both cases from the issue: an existing output file and a recording already in progress. Verify the command's status with echo $?, and consider the work complete when each case exits with status 1 while normal recording behavior remains unchanged.
