Pull request overview

This PR refactors the setBlocking(true) workaround to minimize its scope by only applying it when stdout is piped (non-TTY), and removes the stderr workaround entirely. This is a follow-up to issue #17950.

Changes:

• Added TTY check to conditionally apply the setBlocking(true) workaround only when stdout is piped
• Removed the setBlocking(true) call for stderr
• Updated comments to clarify that the issue occurs specifically with non-TTY stdout and when using pipes
