Fix PDF worker error in packaged Electron apps

The error was: "No GlobalWorkerOptions.workerSrc specified"

Fix:
- Set workerSrc to 'data:,' (empty data URI) instead of ''
- Add disableAutoFetch and disableStream options

This satisfies pdfjs's worker requirement check while running
in fake worker mode for Electron compatibility.
