* 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
By changing output esbuild setting for Markdown preview scripts to iife,
prevents global namespace pollution and reduces possibility of breaking
the preview by contributions from other extensions.
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
