Changes
This adds support for multiple Astro dev servers running simultaneously. Previously, trying to start a second server errored out because the fixed default ports were already in use. Now, when the default ports are in use, a random port is chosen.
Testing
I've tested this manually by running two of the examples in the repo at the same time. Not sure if this can be automatically tested against, but if it needs to be, I would like some pointers.
