Fix WorkerAPI interface implementation - align init signatures

- Update jsEval.worker.ts to accept optional interruptBuffer parameter
- Update ruby.worker.ts to accept optional interruptBuffer parameter
- Update pyodide.worker.ts to handle optional interruptBuffer safely
- All workers now properly implement the WorkerAPI interface
