Detailed Description

Structure-of-Arrays (SoA) storage for 2D mesh boundary conditions.

Stores per-edge boundary condition type, parameters, and cumulative flux tracking. Arrays are flat 2D [tri * 3 + edge_local], sized to n_triangles * 3 (matching edge_flux, edge_length, etc.).

Boundary types:

• WALL: Zero-flux (default). No water crosses the boundary.
• NORMAL_FLOW: Manning outflow based on bed slope at the edge.
• SPECIFIED_STAGE: Prescribed water surface elevation (constant or time-varying via timeseries).
