[Feature Request]: Prompt queue resilience

[webfiltered]

Is there an existing issue for this?

• I have searched the existing issues and checked the recent builds/commits

What would your feature do ?

Add an option for prompt queues to survive core restart by residing in session data. This would effectively involve prompt queue export / import.

Proposed workflow

1. Enable setting
2. Queue 30 unique prompts
3. Crash ComfyUI core, accidentally kill the process/window, or simultaneously trip over all of your server's redundant power cords
4. Recover from catastrophe
5. Click "restore queue" button
6. async foreach prompt queue

Additional information

Original request:

Saving the queue, or at least preserving it [should] a restart of the python/comfy console be needed in a session would be [extremely] helpful I think. [...] It only took a restart to continue on, but once the console/server window is closed the queue will disappear.
