Dynamic preview method per task

[huchenlei]

Feature Idea

Each queued task can spcify its own preview method instead of relying on a static preview method set via server launch args.

This should enables selecting preview method by adjusting frontend settings without restart the server.

Existing Solutions

https://github.com/ltdrdata/ComfyUI-Manager has a UI selection to pick preview method. However, it requires restart to take effect.

The preview method selection in ComfyUI-Manager is applied immediately without restarting the server.
However, it does not affect the inference currently in progress and will only apply to the next inference.
