Having an explicit `"files"` definition will allow us to fingerprint
dependencies in `wireit` more granularly. This avoids problems
that can be caused by different source files and directories that
trigger a rebuild in a dependee before a dependent finishes.
We can use a PNPM hook to make sure that the dependencies
are accounted for in the fingerprint. This script scans through
all of the packages with Wireit and adds the outputs for
linked dependencies.
