**refactor(tests): consolidate and replace outdated environment test scripts**

- Removed obsolete scripts: `test-all-environments.js`, `test-fallback-function.js`, `test-fallback-simple.js`, `test-fix.js`, `test-tensorflow-textencoder.js`, `test-unified-encoding.js`, and `test-worker-utils.js`.
- Introduced `scripts/comprehensive-test.js` as a unified testing script covering all environments: Browser, Node.js, and CLI.
- Added `examples/cli-wrapper-example.js` to demonstrate a proper CLI implementation with TensorFlow.js initialization.

This refactor simplifies the testing structure by consolidating redundant scripts into a single comprehensive script while ensuring robust cross-environment coverage.
