Detailed Description

Kinematic wave routing solver — batch-oriented design.

Port of legacy kinwave.c, restructured for data-oriented execution:

     1. **Batch geometry** — uses XSectGroups to pre-compute section
        factors for all conduits before solving
     2. **Per-conduit Newton** — the continuity equation solve is
        inherently per-conduit (each converges independently), but
        conduits are grouped by shape so the section-factor evaluations
        within Newton can also be batched per group
     3. **Batch state update** — inlet/outlet areas and flows updated
        for all conduits in contiguous sweeps

     Weighted finite-difference scheme:
       WX = 0.6 (space weighting)
       WT = 0.6 (time weighting)
