`pqcrypto-classicmceliece` is unmaintained: upstream PQClean project being archived

Details

This crate provides Rust bindings to the Classic McEliece key encapsulation mechanism via C implementations from [PQClean](https://github.com/PQClean/PQClean). The PQClean project is being archived in or after July 2026 (see [PQClean/PQClean#604](https://github.com/PQClean/PQClean/issues/604)), after which no further security patches or bug fixes will be applied to the upstream implementations.

As a result, this crate will no longer receive updates. Users should migrate to actively maintained alternatives.
