simd: trampoline hpc::cascade as ndarray::simd::cascade

[AdaWorldAPI]

What

One re-export: pub use crate::hpc::cascade; inside src/simd.rs, making the Belichtungsmesser surface (Cascade::expose → Band, recalibrate(ShiftAlert), PackedDatabase, adaptive_resolution, RankedHit, PreciseMode) reachable as ndarray::simd::cascade::*.

Why

The consumer stack enforces "all SIMD from ndarray::simd" (the simd-savant invariant). The banded exposure-meter machinery lives under crate::hpc::cascade, so consumers computing distribution-shape / percentile-rank payloads (the Prozentrang work in the downstream stack) had no sanctioned path to it. This follows the established trampoline pattern already used for hpc::bitwise, hpc::fft, hpc::fingerprint, hpc::quantized, hpc::cam_pq, and hpc::heel_f64x8 in the same section of simd.rs.

Whole-module alias rather than an item list, so future cascade items surface without further re-export edits. simd and hpc share the identical std feature gate (lib.rs:238 / lib.rs:498), so no additional cfg is needed.

Verification

• cargo clippy --lib -- -D warnings — green (compiles the re-export, proving path resolution)
• cargo fmt --check — clean

Poem

A rabbit hops through SIMD light,
And finds cascade paths just right.
One re-export, neat and small,
Makes the search API available to all.
