- Introduced `test-fallback-function.js` and `test-fallback-simple.js` to validate `executeInThread` fallback functionality with both named and anonymous compute-intensive functions. - Added `test-tensorflow-textencoder.js` for TensorFlow.js and TextEncoder tests in a Node.js environment. - Created `test-tensorflow-textencoder.html` for browser-based TensorFlow.js and TextEncoder tests. - Implemented cross-environment test support in `cli-package/src/test-tensorflow-textencoder.ts` for CLI functionality. - Enhanced `src/utils/embedding.ts`, `textEncoding.ts`, and `brainy-wrapper.js` to include updated global `TextEncoder` and `TextDecoder` utilities for compatibility and worker improvements. - Standardized and expanded utility methods in `PlatformNode` for broader support, including `isFloat32Array` and `isTypedArray` checks. - Updated Node.js requirement to `>= 24.4.0` across documentation and configuration files for compatibility improvements. This update introduces comprehensive testing for fallback mechanisms, TensorFlow.js, and TextEncoder across multiple environments, ensuring robustness and compatibility.
