fix(#398): remove unused Array1/ArrayView1 imports from svm/mod.rs

[Mec-iS]

Summary

Follows up on the dead-code cleanup in #398.

After removing pub mod search; from svm/mod.rs, two imports that were only needed by the deleted svm/search/ subtree were left behind:

// removed
use crate::linalg::basic::arrays::{Array1, ArrayView1};

Neither Array1 nor ArrayView1 are used anywhere in svm/mod.rs itself — they were only transitively needed by svc_params.rs / svr_params.rs. Leaving them in place triggers an unused-import warning (or #[expect] failure under the stricter lint setup introduced in the cleanup commits).

Changes

• src/svm/mod.rs — removed the stale Array1 / ArrayView1 import line
