/**
 * Bootstrap: downloads native binary for @matrix-org/matrix-sdk-crypto-nodejs

 *
 * This is needed because opencode's npm doesn't run postinstall scripts.
 * The binary is cached in the plugin's node_modules, so it only downloads once.
 *
 * Must be imported BEFORE any import from matrix-bot-sdk.
