I have a few obvious followups from here:

1. probably need default build/etc to ignore non-packages (e.g. demos)
2. it'd be valuable to break out the sentry integration into its own package - will just clean up some deps in there and promotes what we want

[dcramer]

Oh one other learning I had recently: tsup (or tsdown now) is a lot easier for a lot of bundling. Might be worth adopting that as well.

Common footgun in Turbo: have to define the env variables that the build requires. There's some implicit ones it gives you, but thats why the fossilize build was failing.
