* Combine esbuild scripts
This combines the various build scripts used for building webview/notebook content. This should make it easier to update settings for them
As part of this, I also fixed the script so that on watch it restarts automatically on syntax errors instead of exiting
* Migrate other build script
* Fixing math build script
Revert "Revert e7fffbf1c9169087f1098aedfe54c59c079fa3ac"
This reverts commit 6786b0ad7d.
Two changes:
- Lazy import parcel/watcher
- Add `@parcel/watcher` as a dev dep in extensions folder so that we pull in correct version for build os
