Functions
void	openswmm::input::handle_junctions (SimulationContext &ctx, const std::vector< std::string > &lines)
	Parse [JUNCTIONS] into NodeData + node_names.
void	openswmm::input::handle_outfalls (SimulationContext &ctx, const std::vector< std::string > &lines)
	Parse [OUTFALLS] — sets outfall-specific fields for nodes of type OUTFALL.
void	openswmm::input::handle_dividers (SimulationContext &ctx, const std::vector< std::string > &lines)
	Parse [DIVIDERS] — sets divider-specific fields.
void	openswmm::input::handle_storage (SimulationContext &ctx, const std::vector< std::string > &lines)
	Parse [STORAGE] — adds storage nodes and their geometry.
void	openswmm::input::handle_coordinates (SimulationContext &ctx, const std::vector< std::string > &lines)
	Parse [COORDINATES] — fills spatial.node_x / node_y.
