Answer 1

Set the current working directory to app. Select all subdirs and files of assets. Set the destination to dest.

grunt.initConfig({
    copy: {
        dist: {
            cwd: 'app',
            src: ['assets/**/*'],
            dest: 'dist/',
            expand: true
        }
    }
});

grunt.loadNpmTasks('grunt-contrib-copy');
grunt.registerTask('default', ['copy:dist']);
