🧹 Remove dead commented-out ort._selectedBackend assignment

[ysdede]

🎯 What: Removed commented-out dead code (ort._selectedBackend = backend;) and its associated duplicate comments in src/backend.js.
💡 Why: As the inline comment indicated, the ort object is no longer extensible in newer versions of ONNX Runtime Web. Leaving this dead code and duplicated comments clutters the file and provides no value. Removing it improves readability and general code health.
✅ Verification: Verified syntax correctness by running node --check src/backend.js. As this patch only removes comments, it introduces zero risk of functional changes or regressions.
✨ Result: A cleaner src/backend.js with redundant comments removed, improving maintainability.

Old comments cluttering the load,
Away they hop, no longer needed,
The backend runs, clean and heeded!
