Find Java expression wrappers

Report each explicit Java cast or expression parentheses with its actual direct operand UUID, source range and independently nullable type. Preserve nested wrappers and repeated physical occurrences without flattening expressions or changing their direct kinds. Include ControlParentheses only as the actual direct TypeCast expression operand; exclude cast-type and control-statement delimiters and documentation. Does not evaluate values, change source, infer taint or establish runtime flow or dispatch.
