Parse MTTS from telnetlib3 writer during connection and store capabilities on Player.caps field. Add convenience property Player.color_depth that delegates to caps.color_depth for easy access by rendering code. Changes: - Add caps field to Player with default 16-color ANSI capabilities - Parse MTTS in server shell after Player creation using parse_mtts() - Add Player.color_depth property for quick capability checks - Add tests verifying Player caps integration and color_depth property
