fix: add @objectstack/spec to apps/demo deps and promote to runtime dep in @objectql/types

The Vercel serverless function failed at runtime with ERR_MODULE_NOT_FOUND
because @objectstack/core could not resolve @objectstack/spec after pnpm
symlinks were dereferenced by patch-symlinks.cjs.

1. apps/demo/package.json: add @objectstack/spec ^3.2.8 as devDependency
   so it is present in node_modules and dereferenced for Vercel bundling.

2. @objectql/types/package.json: move @objectstack/spec and zod from
   devDependencies to dependencies because compiled JS output contains
   runtime imports via z.infer<typeof Data.X> patterns.

 ## [Unreleased]
 
+### Fixed
+
+- **`apps/demo`** — added missing `@objectstack/spec` devDependency. The Vercel serverless function failed at runtime with `ERR_MODULE_NOT_FOUND` because `@objectstack/core` could not resolve its `@objectstack/spec` dependency after pnpm symlinks were dereferenced by `patch-symlinks.cjs`. Adding the explicit dependency ensures the package is present in the bundled `node_modules/`.
+- **`@objectql/types`** — moved `@objectstack/spec` and `zod` from `devDependencies` to `dependencies`. The compiled JS output contains runtime imports of `@objectstack/spec` (via `z.infer<typeof Data.X>` patterns), so they must be declared as production dependencies.
+
 ### Added
 
 - **`apps/demo`** — standalone Vercel-deployable demo application ([#issue](https://github.com/objectstack-ai/objectql/issues)):
