Detailed Description

Dynamic wave routing solver — batch-oriented St. Venant equations.

Port of legacy dwflow.c + dynwave.c, restructured for batch execution:

     **Per Picard iteration:**
     1. **Batch geometry** — XSectGroups pre-computes a1[], a2[], aMid[],
        rMid[], wMid[] for ALL conduits simultaneously (shape-grouped,
        SIMD-vectorisable)
     2. **Batch momentum** — friction slope, head gradient, inertial terms
        computed as array operations over pre-computed geometry (no xsect
        dispatch in the inner loop)
     3. **Scatter** — link flows transferred to node inflow/outflow
     4. **Node depth update** — per-node (Picard convergence check)

     Uses theta-implicit scheme with Preissmann slot for surcharge,
     inertial damping based on Froude number, and under-relaxation.

Note: Legacy reference: src/legacy/engine/dwflow.c, dynwave.c
