CLI parse hangs reading stdin when no argument provided and stdin is a TTY

[ajitpratap0]

Description

Running gosqlx parse with no arguments and no piped input causes it to hang indefinitely reading stdin.

Reproduction

gosqlx parse
# hangs forever, no prompt, no usage hint

Expected

When stdin is a TTY (interactive terminal) and no argument is given, the command should print usage/help and exit instead of silently waiting for input.

Workaround

Always provide an argument: gosqlx parse "SELECT 1" or pipe: echo "SELECT 1" | gosqlx parse -
