Vite plugin: Show auxiliary worker name that caused error

[nzakas]

One of my biggest frustrations dealing with auxiliaryWorkers in the Vite plugin is how error messages don't indicate the worker from which they originate. When I try to start Astro with a bunch of workers and one of them crashes, there is no indication which worker caused the crash, leading me down a rabbit hole that takes forever to debug.

Something very clear like "Error in :" would save me a lot of time.
