RUSTSEC-2026-0131 Double-free in `Chomp::inner()`

Chomp::inner uses std::ptr::readunaligned to move out the value from a raw pointer. If the original value is an owned type e.g. Box, calling inner moves out the ownership, but the original variable will still be dropped at the end of its scope. This causes the same heap memory to be freed twice,...

RUSTSEC-2026-0128 Double-free and use-after-free in `Keys::next()`
