Another one that I noticed.
The dist structure is very simple rn, so unlikely to run into orphaned
files as you're emitting a single built artifact which wil be
overwritten on build, but I always prefer to do clean builds as
"hygiene".
I had a dirty dist personally after local development and testing some
things, as an example.
Alternatives could be to create a `clean` script with cross platform
`rimraf dist`
