Fix one error and all warnings on MSVC 2026 The error is "C1001: Internal compiler error." in uci.cpp on line 370 of master. For some reason the compiler can't handle the std::size(hashfullAges) inside the lambda. Older MSVC versions had no problem. Most of the warnings are due to implicit type conversions "conversion from type A to type B, possible loss of data" many of which have been present for a while. closes https://github.com/official-stockfish/Stockfish/pull/6464 No functional change
