Summary

Adds multi-format build outputs (ESM index.mjs, CJS index.js, and global/IIFE index.global.js), enabling direct browser usage via both <script type="module"> and classic <script> tags. Exposes getCurrentBrowserFingerPrint as a window global when loaded via the global build. Updates export map, adds tsup bundling, updates README with new CDN examples, and adds a changelog entry. Resolves inability to import the library from a CDN previously reported (window.getCurrentBrowserFingerPrint is not a function and missing named export errors).

Type of change

• New feature (multi-format bundles / global exposure)
• Docs update (README + changelog)
• Chore / Maintenance (build pipeline/tooling)
• Bug fix
• Breaking change

Checklist

• Code builds locally (npm run build)
• Linting/format (N/A – project has no configured linter; manual review performed)
• Updated documentation (README/changelog updated)
• Added tests or explanation why not (No existing test infra; deterministic functions unchanged aside from packaging)
• Version bump NOT included (NOTE: version already bumped to 2.2.0 as part of this branch to publish multi-format build)

How to test

1. Install deps: npm install
2. Build: npm run build
3. Confirm outputs exist: lib/index.mjs, lib/index.js, lib/index.global.js, lib/index.d.ts
4. Node CJS: node -e "const { getCurrentBrowserFingerPrint } = require('./lib'); console.log(typeof getCurrentBrowserFingerPrint);" should print function.
5. Node ESM: node --input-type=module -e "import { getCurrentBrowserFingerPrint } from './lib/index.mjs'; console.log(typeof getCurrentBrowserFingerPrint);" should print function.
6. Browser (module):

<script type="module">
  import { getCurrentBrowserFingerPrint } from 'https://cdn.jsdelivr.net/npm/@rajesh896/broprint.js@2.2.0/lib/index.mjs';
  getCurrentBrowserFingerPrint().then(console.log);
</script>

7. Browser (global):

<script src="https://cdn.jsdelivr.net/npm/@rajesh896/broprint.js@2.2.0/lib/index.global.js"></script>
<script>
  getCurrentBrowserFingerPrint().then(console.log);
</script>

Screenshots / Logs

N/A – library build / API unchanged; packaging only.

Related issues

Fixes: CDN usage errors (unreported issue numbers) regarding missing named export and undefined global.

Additional context

• Introduced tsup (devDependencies) for concise multi-target bundling.
• Export map now aligns Node (CJS) and modern bundlers (ESM).
• Added global assignment guard (if (typeof window !== 'undefined' ...)).
• README cleaned: removed duplicate install section & outdated crypto-js note.
