refactor: add final to all method/constructor parameters (MethodArgumentCouldBeFinal)

- Add final to every method/constructor parameter that is not assigned in the method body
- Handle annotations, varargs, generics, throws clauses
- Skip record components, lambdas, catch clauses, enum constructors
- Skip parameters that are reassigned in the method body
