**feat(cli, workers): introduce text encoding patches and worker improvements**

- Added `cli-package/brainy-wrapper.js` to patch global `TextEncoder` and `TextDecoder` for Node.js environments, ensuring compatibility with TensorFlow.js.
- Implemented unified text encoding utilities in `cli-package/src/utils/textEncoding.ts` for cross-environment consistency.
- Enhanced `src/worker.js` and introduced `src/worker.ts` to improve worker execution with better function serialization and error handling.
- Updated `package.json`:
  - Modified the `build` script to include a patch for `TextEncoder`.
  - Added `test-all` script for multi-environment testing.
  - Introduced the Puppeteer dependency for browser testing.
- Created a favicon generation script `scripts/create-favicon.js` using a base64-encoded icon.
- Added `scripts/test-all-environments.js` to run automated tests across Node.js, browser, and CLI environments.
- Enhanced `src/utils/workerUtils.ts` to support improved fallback mechanisms and robust worker pooling.

This update improves the project's compatibility across environments, refines worker functionalities, and adds comprehensive testing support for reliability.

 ## Testing
 
+### Testing All Environments
+
+Brainy provides a comprehensive test script that verifies the library works correctly in all supported environments (browser, Node.js, and CLI):
+
+```bash
+# Test the library in all environments
+npm run test-all
+```
+
+This script:
+1. Builds all packages (main, browser, CLI)
+2. Runs Node.js tests (worker tests and unified text encoding test)
+3. Starts a local HTTP server and runs browser tests using Puppeteer (headless browser)
+4. Runs CLI tests by installing the CLI package locally and testing basic commands
+
+The test results are displayed with color-coded output for better readability.

 ### Testing the CLI Package Locally
 
 Before publishing the CLI package to npm, you can test it locally to ensure it works as expected:
