// External packages — NOT bundled into the library output.
//
// We deliberately bundle most npm dependencies (hono, ai, @ai-sdk/*, effect,
// zod, ulid, remeda, decimal.js, qrcode-generator, ai-gateway-provider) so
// `dist/index.js` is a self-contained Workers ESM module. Consumers using the
// @cloudflare/vite-plugin in particular don't follow bare imports inside
// pre-built workspace bundles, so leaving these as external broke
// same-worker integrations with "No such module 'hono'" at runtime.
//
// Kept external on purpose:
//   • cloudflare:workers / node:* / node built-ins — provided by the
//     Workers runtime, not packageable.
//   • @cloudflare/shell, @cloudflare/worker-bundler — Cloudflare runtime
//     libraries that use special Workers features and may need to remain
//     the consumer's exact version.
//   • drizzle-orm — used by `src/project/project.sql.ts`. NOT a declared
//     dependency of @space-do/space; consumer is expected to install
//     drizzle-orm themselves if they exercise that code path.
//   • isomorphic-git + transitives — pulled in by @cloudflare/shell at
//     runtime; must resolve to the consumer's copy to share state.
