pnpm's isolated store prevents native post-install scripts from finding
their dependency binaries (node-pre-gyp, prebuild-install). This causes
@discordjs/opus and @lng2004/node-datachannel to fail during pnpm install.
Enabling shamefully-hoist flattens node_modules so native scripts can
resolve their dependencies correctly.
