Count how many ships are in an area right now, broken down by ship-type category and by whether they are moving or stationary. Answers "how many vessels are in this area", "how many tankers are in the Gulf of Finland", "ship traffic count in a bounding box", "how many vessels are anchored off Helsinki". Give EITHER a circle (latitude, longitude, radius_km) OR a bounding box (min_lat, max_lat, min_lon, max_lon). Returns total, by_category counts (cargo, tanker, passenger, fishing, other), moving versus stationary using a 0.5-knot threshold, and the data timestamp. COVERAGE IS REGIONAL: Fintraffic AIS receivers over Finland and the surrounding Baltic Sea; an area elsewhere in the world counts zero. Example: min_lat 59.3, max_lat 60.5, min_lon 22.0, max_lon 28.0 for the Gulf of Finland; or latitude 60.15, longitude 24.95, radius_km 50 for Helsinki.
