契约
- assert Mustermann::Pattern#hash computes bitwise XOR (^) of class, string, and options hashes
- assert identical patterns produce equal hash codes and satisfy eql? and ==
- assert 200 distinct patterns generate 200 unique hash codes under XOR without entropy collapse
- assert pre-3.1.1 bitwise OR (|) implementation collapses entropy and causes >40% hash collisions
- assert Pattern instances function as distinct keys in Ruby Hash lookup
- assert Mustermann pattern matching extracts named parameters correctly
