Implement queue/darray product() reduction (including class property paths) via new %queue/product/v and %queue/product/prop/v opcodes, with elaboration/codegen support and regressions for queue, dynamic-array, and class-property usage.
Made-with: Cursor
Enable unique and unique_index locator methods with `with (...)` for queues, dynamic arrays, and class dynamic-array properties, including VVP opcode/runtime support and regression coverage.
Made-with: Cursor
Handle IVL_EX_ARRAY_PATTERN in object evaluation by constructing a dynamic-array object and filling elements, so direct class property assignments like c.d = '{...}; codegen correctly without requiring a temporary variable.
Made-with: Cursor
Add class dynamic-array property support for locator methods (find*, unique*, min/max, with predicates) by elaborating dynamic-array property method calls to queue-method sfuns. Extend VVP property paths to treat property values as queue-or-darray sources, not queue-only, and fix object-stack handling in property locator loops so temporary accumulator objects do not hide the class object.
Add regression coverage for class dynamic-array property locators and update locator-method test documentation/listing.
