Adds the Swap Arguments Order Replacement (SAOR) mutator that generates mutations by swapping function call arguments when they share the same type. This helps detect test suites that don't verify argument ordering. Closes crytic#2947 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The _mutate() method returns {'patches': {file: [...]}} not {file: [...]}.
