**feat(patch): enhance TextEncoder/TextDecoder compatibility for TensorFlow.js**

- Refactored `applyTensorFlowPatch` in `textEncoding.ts` to introduce a unified `Platform` class supporting both Node.js and browser environments with native `TextEncoder`/`TextDecoder`.
- Modified global object handling to target `PlatformNode` in Node.js and `PlatformBrowser` in browser environments.
- Added `getTextEncoder` and `getTextDecoder` utility functions to simplify text encoding/decoding across platforms.
- Introduced `setup.ts` to apply environment patches before other modules load.
- Updated CLI entry points (`cli.ts`, `rollup.config.js`) to ensure patching precedes TensorFlow.js usage.
- Enhanced test coverage for TextEncoder compatibility with `test-fix.js`.
- Adjusted imports in `test-tensorflow-textencoder.ts` to align with the updated `./utils/textEncoding.js`.
- Streamlined constructor definitions in `Platform` for improved maintainability.

This update ensures robust compatibility for TensorFlow.js by patching and standardizing text encoding/decoding functionality across environments.
