1.8.8 crashes when widget fails to update mid-restart/reinitialization

Describe the bug

Looks like there's little chance of recovery when a widget fails to update, it brings the whole thing down rather than just waiting to run the next update.

Thank you for reporting this issue @working-name!

I can see from the logs that YASB is crashing when the GPU widget encounters a timeout during a screen reinitialization:

[ERROR] [MainThread] [root/gpu.py:141]: Error updating shared GPU data: Command ... timed out after 2 seconds

The nvidia-smi timeout occurs while YASB is restarting due to a screen update, and instead of gracefully handling the error, it results in a Qt6Core.dll crash (BEX64 exception). This suggests the error handling during widget updates, especially during reinitialization, needs improvement.

Potentially related issue:

• Issue Weather widget crashes YASB when tooltip enabled (ValueError: invalid literal for int() with base 10: '0.0') #690 also involves widget crashes, though with a different widget (Weather widget)

The developers will need to investigate why the GPU widget timeout causes a Qt crash during the restart sequence. This appears to be a more systemic issue with error recovery during reinitialization.

OK, I have added a worker on a separate thread, which should prevent blocking or crashing d3a82bc
