Fixed all test failures to achieve 100% test pass rate (124/124 passing):
- Fixed King.test.js invalid Jest environment docblock syntax error
- Added setupInitialPosition() calls to tests expecting initial board state
- Implemented piece value property (Queen=9) in base Piece class
- Fixed Pawn en passant logic with enPassant flag on moves
- Fixed Pawn promotion logic with promotion flag on promotion rank moves
- Updated Board.getPiece() to throw errors for out-of-bounds positions
- Updated Board.findKing() to throw error when king not found
