This PR introduces the RNM (Remove Negation) mutator to the existing mutator set.
The mutator removes logical negation (
!) from unary expressions, enabling mutation testing to evaluate whether tests correctly detect inverted boolean logic.Examples
require(!paused)→require(paused)assert(!(x > 0))→assert((x > 0))
