`node --watch` without script path does not fail since v25.1.0

Subsystem

watch-mode

What steps will reproduce the bug?

$ node --watch

How often does it reproduce? Is there a required condition?

*

What is the expected behavior? Why is that the expected behavior?

Note: The --watch flag requires a file path as an argument and is incompatible with --run or inline script input, as --run takes precedence and ignores watch mode. If no file is provided, Node.js will exit with status code 9.

$ node --version
v25.0.0
$ node --watch
node: --watch requires specifying a file
$ echo $?
9

What do you see instead?

$ node --version
v25.1.0
$ node --watch

> .exit
