Chess Environment for OpenEnv.

This module provides OpenEnv integration for chess, using the moonfish
chess engine for position evaluation and opponent play.

Example:
    >>> from envs.chess_env import ChessEnv, ChessAction
    >>>
    >>> # Connect to a running server or start via Docker
    >>> env = ChessEnv.from_docker_image("chess-env:latest")
    >>>
    >>> # Reset and interact
    >>> result = env.reset()
    >>> print(result.observation.fen)
    >>> print(result.observation.legal_moves)
    >>>
    >>> result = env.step(ChessAction(move="e2e4"))
    >>> print(result.reward, result.done)
    >>>
    >>> # Cleanup
    >>> env.close()
