BREAKING CHANGE: The build output has changed slightly. This isn't a huge deal, and no steps are required for users unless you're doing something weird with the output files after a build.
Before:
```
.output/
<target>/
chunks/
popup-<hash>.js
popup.html
```
After:
```
.output/
<target>/
popup.html
popup.js
```
This applies for all HTML files, not just the popup.
