fix(rules): scale dirty trick duration and drop nauseated

PF1e (APG Dirty Trick): "This condition lasts for 1 round. For every 5
by which your attack exceeds your opponent's CMD, the penalty lasts 1
additional round" — rounds_left = 1 + margin//5. The RAW condition list
(blinded, dazzled, deafened, entangled, shaken, sickened) does not include
nauseated, so it is removed from TrickCondition. README updated.
