I think this will work:

- "What's the purpose of your visit?" - "I will be looking for a job in the U.S." - "But you have a visitor's VISA here" - "Oh.. mmm.. but I am coming here to work" - "I am sorry this is not going to work out"

Or, rather than lying to the border agent (which I believe is a crime in the US, isn't it?), she could simply tell the truth: that she's visiting her husband and that she'll most likely be coerced to overstay her visa.

That should get her entry denied too.

Precisely. Not sure if it is a crime or not (probably!), but lying is never a good idea, specially to an immigration agent.

Just telling the truth should suffice. The only issue is if it will cause trouble later on should she try to enter again. I assume it would.

EDIT: There is probably a 'alien will probably overstay' flag somewhere. Not a 'alien will overstay provided she is still married to an out of status alien'.

This seems a quite sane and simple answer.
