Iran is currently having inter-faction power struggles going on. That's why one day they agree to no executions and then they execute the wrestler. The diplomatic faction was negotiating something the hard-liners weren't willing to commit to.
The theocracy rushed to name the new Ayatollah who hasn't been seen or heard, while the IRGC bombing the hotels, airports, and oil facilities of neighboring Arab countries.
Trump can always resume the bombing if he believes he's dealing with people who have no control inside Iran. At least he can say he tried, and a one-day pause bought him some recovery in the stock market.
