Detailed Description

Structure-of-Arrays (SoA) storage for all node types.

Replaces the global Node[] array and TNode/TJunct/TOutfall/ TStorage structs from src/solver/objects.h with a data-oriented layout. Parallel arrays improve cache efficiency for the hydraulic solver, which typically touches a subset of fields across all nodes.

Node types supported:

• JUNCTION — standard junction node
• OUTFALL — open boundary condition
• DIVIDER — flow diversion node
• STORAGE — storage unit (pond/tank)
