/**
 * Determines if a project is publishable based on its configuration and file structure.
 *
 * This function checks if the given project is a library, is buildable, and contains a non-private `package.json` file
 * at the project root. The function utilizes a `TreeAdapter` to interact with the file system structure provided by `tree`.
 *
 * @param {TreeLike} tree - The file system abstraction used to access files within the project.
 * @param {ProjectConfiguration} project - The configuration object of the project, including properties like the project type and root directory.
 * @returns {boolean} Returns `true` if the project is a library, is buildable, and has a non-private `package.json` file; otherwise, returns `false`.
