### Added

- Add dedicated ESM, CommonJS, Node.js, and browser distribution entry points.
- Add streaming support to the native Node.js SHA-256, SHA-224, and HMAC implementations.
- Add distribution contract tests and real browser Web Worker tests with Playwright.
- Add Node.js 16, 18, 20, 22, and 24 runtime tests against the packed npm artifact.

### Changed
- Refactor the implementation into environment-independent core and Node.js modules.
- Use the native Node.js `crypto` implementation for hashing and HMAC.
- Load the package version automatically when generating distribution banners.
- Export unminified ESM source directly and build only CommonJS and browser/minified distributions.
- Replace `expect.js`, NYC, Tiny Worker, and UglifyJS with Node.js assert, c8, Playwright, and Rollup/Terser.
- Build automatically before `npm pack` and `npm publish`.
- Throw error if update after finalize

### Removed
- Remove runtime CommonJS, AMD, Node.js, Web Worker, and ArrayBuffer environment switches from the core implementation.
- Remove legacy environment flags and obsolete compatibility polyfills.
- Remove the old generated `sha256.mjs` and `sha256.node.mjs` entry points.

 ## Usage
-You could use like this:

+### Browser
+Load the minified UMD build to expose `sha256` and `sha224` as globals:
+
+```HTML
+<script src="sha256.min.js"></script>
+<script>
+  console.log(sha256('Message to hash'));

+
+### CommonJS
+```JavaScript
+const sha256 = require('js-sha256');
