Class Default Member Initializers for Option The Option class in ucioption.h contains several members (min, max, idx) that are initialized to 0 in initializer lists across multiple constructors in ucioption.cpp. Moving these default values directly into member declarations inside ucioption.h eliminates redundant constructor initializer list entries. closes https://github.com/official-stockfish/Stockfish/pull/7031 No functional change
