**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.
