Please describe the problem you're trying to solve

cp has protection against copying a directory into itself.

This is not present in yazi resulting in an operation running forever.
Of course you could just quit yazi, so it is not an urgent feature, just a nice addition to yazi.

Would you be willing to contribute this feature?

• Yes, I'll give it a shot

Describe the solution you'd like

A warning message when you are about to copy a directory into itself.
