examples project fails without pre-building workspace packages

Problem

examples:vite fails without pre-building workspace packages.

@react-simplikit/mobile's exports in package.json points to ./dist/index.js, which doesn't exist until the package is built.

[commonjs--resolver] Failed to resolve entry for package "@react-simplikit/mobile".
The package may have incorrect main/module/exports specified in its package.json.

Both Vite and Next.js resolve exports strictly and require the built output to exist.

Possible Solutions

1. Root scripts with pre-build — e.g. "example:vite": "yarn build && yarn workspace with-vite dev". Simple but rebuilds every time.
2. Vite alias / Next.js transpilePackages to source — Configure alias or transpilation to point directly to src/index.ts. Avoids build step but couples the example to source structure.
3. Monorepo tooling (Turborepo, etc.) — Manages dependency graph so packages are built before dependents. Proper solution but may be overkill for current scale.
4. Conditional exports for development — Add a development condition in exports pointing to source, used only in dev.

Reproduction

# Clean state (no dist/)
rm -rf packages/mobile/dist packages/core/dist

# execute vite server
yarn example:vite
