[board, moves, position] Move make_move routines to moves crate Declare a MakeMove trait and export it from chessfriend_moves. Declare a BoardProvider trait that both Board and Position implement. Implement the MakeMove trait for all types that implement BoardProvider, and move all the move making code to the moves crate. This change makes it possible to make moves directly on a Board, rather than requiring a Position. The indirection of declaring and implementing the trait in the moves crate is required because chessfriend_board is a dependency of chessfriend_moves. So, it would be a layering violation for Board to implement make_move() directly. The board crate cannot link the moves crate because that would introduce a circular dependency. 2025-05-31 19:01:20 -07:00			`// Eryn Wells <eryn@erynwells.me>`
