Subject: [PATCH] Fix main-entry type re-exports failing under bundler
 resolution
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Since 0.4.0 the dist/ tree contains both Vite-emitted dist/<name>.js/.cjs
files and tsc-emitted dist/<name>/index.d.ts folders side by side. With
both on disk, TypeScript's `bundler` module resolution prefers the file
over the folder, so `dist/index.d.ts`'s `export * from './primitives'`
walks into `./primitives.js` (no types) and silently drops every symbol.

Net effect: every consumer importing primitives/layout/charts/visualization/
inputs/display/utils/assets/theme symbols from the main entry of ui-kit
@>=0.4.0 fails type-check with "Module '@policyengine/ui-kit' has no
exported member 'Badge'" (and the same for Skeleton, Container, Button,
…).

Fix: pin the source re-exports to the explicit `./<name>/index` folder
path. TypeScript's bundler resolution then walks into the folder and
finds the types. Verified locally with a fresh `tsc --noEmit` against a
file:-installed build of this branch.

Subpath imports (`@policyengine/ui-kit/primitives`) were unaffected because
the `exports` map already pins them to the index.d.ts folder path. No
runtime change — Vite's emit and the package's `exports` map are
unchanged. Only the .d.ts re-export paths shift.

See https://github.com/microsoft/TypeScript/issues/52146 for the upstream
ambiguity.

+Main-entry type re-exports now resolve from a TypeScript `bundler` consumer. Since 0.4.0 the dist/ tree contains both Vite-emitted `dist/<name>.js`/`.cjs` files and tsc-emitted `dist/<name>/index.d.ts` folders side by side. With both on disk, TypeScript's `bundler` module resolution prefers the file over the folder and reports `Module '"@policyengine/ui-kit"' has no exported member 'Badge'` (and the same for every primitive/layout/charts/visualization/inputs/display/utils/assets symbol) from the main entry. Pinning the source re-exports to the explicit `./<name>/index` folder path forces folder resolution and exposes types correctly. Subpath imports (`@policyengine/ui-kit/primitives`) were unaffected.
