Any other information relevant to this pull request? This may include screenshots, references, and/or implementation notes.

Implementation Notes:

• Wrapper Strategy: This package acts as an ndarray interface layer. It extracts the underlying data buffer, stride, and offset from the input ndarray and delegates the reversal logic to the base strided implementation.

• API Consistency: The function signature is drev( x ) (unary operator), consistent with standard BLAS conventions for in-place modifications, rather than accepting an array of arrays.

• Stride & Edge Case Handling: Relies on the robust handling within the base @stdlib/blas/ext/base/drev package for negative strides and empty arrays (N=0).

• Type: Validated for double-precision floating-point performance (Float64Array) in benchmarks.

Thanks for the catch. I've updated docs/types/test.ts to use top-level imports, consistent with other packages. Ready for review.
