    Summary: conquer-once's OnceCell lacks Send bound for its Sync trait.

    Details: Affected versions of `conquer-once` implements `Sync` for its `OnceCell` type without restricting it to `Send`able types. This allows non-`Send` but `Sync` types such as `MutexGuard` to be sent across threads leading to undefined behavior and memory corruption in concurrent programs. The issue was fixed by adding a `Send` constraint to `OnceCell`.
