Research direction
Investigate the command module in fastfetch's source code, likely in src/detection/command.c or similar. Look at how fastfetch parses the JSON config and executes commands. Check recent commits that might have affected command output. The issue mentions version 2.30.1, so look at changes around that version. Also check if the issue is related to how stdout is captured or if there's a missing initialization.
