Detailed Description

template<int MaxL>
struct occ::mults::kernel_detail::HermiteAddTable< MaxL >

Precomputed hermite_index addition tables for contraction hot paths.

For each pair of hermite indices (i, j), stores the combined index hermite_index(ta+tb, ua+ub, va+vb) and the three shifted-index variants for force gradients. Replaces ~10 integer ops per hermite_index call with a single array lookup.

Table size: N×N × 4 × 4 bytes. For MaxL=4: 35×35×16 = ~19KB (fits in L1).
