Background agents denied a tool now get a plain denial message instead of confusing don't-ask wording.

What
When a background agent denies a tool because it cannot ask you, the model now sees a plain "Permission to use X has been denied". The older wording about don't-ask mode is kept for that mode only, so the two cases no longer read the same.
Evidence
Permission prompts are not available in this context
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
