Subject: [PATCH] fix: use test-open for /dev/tty instead of -e check

[[ -e /dev/tty ]] returns true even in non-interactive SSH sessions
where the device file exists but cannot actually be opened, causing
'No such device or address' errors. Replace with { true </dev/tty; }
which tests actual openability before redirecting.
