## Summary

Adds new store for tracking outputs lin linear mode and reworks outputs
to display the following: skeleton -> latent preview -> node output ->
job result.

## Changes

- New store for wrangling various events into a usable list of live
outputs
- Replace manual list with reka-ui list box

Getting all the events and stores aligned to happen consistently and in
the correct order was a challenge, unifying the various sources. so
suggestions there would be good
