Various changes that may be of interest

Hi!

Nice project you have here! I am using isoflow for a personal project of mine where I run dynamic simulations for the diagram nodes. For that I needed to do a number of changes to isoflow to support things like re-rendering and modifying connection styling from code multiple times per second. Also I needed ability to hide more of the buttons and such.

Summary:

• NodeIndicatorComponent - I use this to render a gauge next to the node that updates as the simulation runs
• Passing the scene to onModelUpdated - probably hacky but allows me to animate connectors
• Allow selectively hiding more menu items (more planned)
• Some tentative support for parent component rerendering without breaking Isoflow
• support for error boundary instead of alert popup
• switch jest to vitest (Seems to be less fiddly. Couldn't get jest to work well with the error boundary tests)

I'm creating this PR as a draft to gauge interest and get some initial feedback. I still have a bit of work left before my project is in some kind of useful state and I will need to make a bit more changes.

• Do you want these features? Would you want some of them? Would you prefer that I split them up?
