Formatting only. cargo fmt --check was already failing on main (accel SIMD
kernels, agent, format, migrate, bench); CI now enforces it.

fix(accel): restore f32::EPSILON near-zero-denom guard in cosine_similarity

CI / test (pull_request) Canceled after 0s

Details

The SIMD migration weakened the near-zero-norm guard in all four
clawhdf5-accel cosine_similarity backends (scalar/avx2/avx512/neon)
from `denom < f32::EPSILON` to `denom == 0.0`. Vectors with a tiny
but nonzero norm (denom in (0, 1.19e-7)) fell through to dot/denom
and scored as identical instead of maximally dissimilar, diverging
from the pre-SIMD scalar loop's documented fallback behavior.

Restores the epsilon threshold in all four backends so
`1.0 - cosine_similarity(...)` in hnsw.rs::compute_distance
reproduces the old fallback exactly. Adds regression tests in
clawhdf5-accel and clawhdf5-ann locking in the near-zero-norm case.
