fix: apply terminal output line limits consistently

Apply terminalOutputLineLimit to command output lines as they are received,
rather than only at the end of command execution. Also apply the limit to
terminal output shown in environment details.

This ensures consistent output truncation behavior across all terminal
output paths, preventing potential memory issues from large outputs.
