Subject: [PATCH] fix(directions): show a 996 m leg as 1.0 km, not 1000 m

routeDistanceText checked the raw meters against 1000 but printed them rounded to tens, so 995 m or more read "1000 m". Compare the rounded value so it moves to kilometres.

+- Show a route leg of 995 m or more as 1.0 km. The route summary and step
+  cards kept meters below 1000, then rounded 996 m up to "1000 m"
