- Added `test-browser-worker.html` to demonstrate threading with Web Workers in browser environments. - Added `test-fallback.html` to verify fallback functionality when threading is unavailable. - Created `THREADING.md` to document unified threading implementation, including Node.js Worker Threads, Web Workers, and fallback mechanisms. - Updated Node.js version requirement in `README.md` and `package.json` to `>=24.0.0` for compatibility with improved Worker Threads API. - Enhanced `workerUtils.ts` to implement threading with a worker pool for Node.js and added Web Worker execution logic for browsers. - Enabled environment-aware threading availability in `environment.ts`. - Updated `rollup.config.js` to include CLI configurations for streamlined builds. - Adjusted `.gitignore` to exclude test artifacts and package files. These changes provide comprehensive testing and documentation of threading functionality, improve cross-environment compatibility, and enhance developer workflows.
