// Platform-aware loader for the Wickra Node native binding.
//
// In production (after `npm install wickra`) the actual `.node` binary
// lives inside a per-platform subpackage that npm installs as an
// optional dependency — e.g. `wickra-linux-x64-gnu`. In development
// (after `napi build --platform`) the binary sits next to this file.
// We try the local path first and fall back to the subpackage so the
// same loader works in both modes.
