Subject: [PATCH] **fix(cli): patch TextEncoder for Node.js v24 compatibility**

- Added a fallback mechanism to ensure `TextEncoder` and `TextDecoder` are available in the `util` module for Node.js v24.
- This fix resolves compatibility issues with TensorFlow.js in Node.js v24 environments.
- Synchronized CLI package version to `0.9.21` and updated `@soulcraft/brainy` dependency reference in `package-lock.json`.

This update ensures smoother functionality in Node.js v24 while maintaining version alignment across dependencies.
