PHP's array_column respects calling scope visibility. This change: - Checks scope->canReadProperty() before including a property type - When both __isset and __get are defined, treats inaccessible properties as maybe-accessible (returns generic array) - For non-final classes, accounts for child classes that could override visibility: protected keeps its type (invariant in PHP), private becomes mixed (child can redeclare with any type) - For final classes, inaccessible properties return empty array - Handles NeverType in index position by falling back to integer keys Fixes phpstan/phpstan#13573

For non-final classes, a child class can widen visibility: - protected: type is preserved (invariant in PHP), treat as maybe - private: child can redeclare with any type, treat as mixed For final classes, non-accessible properties return empty array. Add implicit final test for new expression (asFinal via NewHandler).
@Final is just a PHPDoc convention with no runtime enforcement, so a child class can still extend and override property visibility.
