Reformatter doesn't respect line length constraint when there is inner class

For a variable definition where the variable uses inner class

private static final ClusterLauncher.ClusterLaunchResponse CLUSTER_LAUNCH_RESPONSE =
        ClusterLauncher.ClusterLaunchResponse.of(URI, ENVIRONMENT_PARAMS);

the formatter reformatted it to

private static final ClusterLauncher.ClusterLaunchResponse CLUSTER_LAUNCH_RESPONSE = ClusterLauncher.ClusterLaunchResponse
        .of(URI, ENVIRONMENT_PARAMS);

where the first line is longer than the line length constraint

Start by reproducing the formatter behavior with the inner-class variable definition shown in the issue, then trace the formatting path for variable declarations and qualified inner-class types. Done means the reformatted output respects the configured line-length constraint for this example, with coverage for the regression if the repository's existing test structure identifies a suitable location.
