Summary

This PR adds an index.js file under the locales/ directory to explicitly export available locale modules (currently hiIN). This enables imports like:

import { hiIN } from "@toolpad/core/locales";

Motivation

Previously, consumers attempting to import @toolpad/core/locales encountered errors because:

• The module was implemented as a flat file (hiIN.js)
• There was no index.js in the locales/ folder
• The package.json exports field did not expose this path explicitly

but this method matches how Material UI locales are imported.

As a result, valid-looking import paths like:

import { hiIN } from "@toolpad/core/locales";

would fail at runtime

This PR fixes that by introducing an explicit index that re-exports the locales,

Changes

• Added locales/index.js that re-exports hiIN
• No locale logic was changed—just improved how they're consumed

Benefits

• Fixes a broken import path (bugfix)
• Improves DX by enabling clean, named imports
• Easy to scale: new locales can be added via the index file

Notes

This fix avoids having to restructure each locale into its own folder or clutter the exports field with specific entries. It keeps the implementation simple while solving a real usability issue.
