Plans a transit trip from an origin stop to a destination stop using the static route graph. Returns direct options (single route) and 1-transfer options sorted by fewest stops. Use when the user asks 'how do I get from A to B?' or needs route recommendations between two stops. Requires numeric stop codes for both origin and destination; use `get_stops_around_location` first if you only have addresses or coordinates. Does NOT account for realtime service disruptions or live vehicle positions — combine with `get_stop_realtime` for live ETAs after planning.
