This PR prevents license notices being dropped when creating package for
publication.
This can happen when first import in the file is type-only import that
gets removed during build. When there is no empty line between the
license block comment and such import, the comment is treated as related
to the import and gets removed alongside it.
Adding an empty line between copyright notice and the import fixes the
issue.

This PR tidies up the code around performance parsing and what we
respond with from our tools. It introduces the ability to have no
Insights from a trace (relatively rare, but can happen), and also adds
more information to the output in the event that something went wrong.
Previously we just logged errors, but if we respond with them here that
will also help users report issues and increase the chances that we can
debug them.
