 * Shared tsup preset for every package in the Astroid SDK monorepo.

 * Workspace dependencies (`@astroid/*`) and declared peer dependencies are kept
 * external so each package stays thin and installs resolve through the pnpm
 * workspace symlinks. Build order is topological (pnpm -r), so a package's
 * dependencies are always compiled — with their `.d.ts` — before it builds.
