feat: show librad project repository (#86)

To show the actual source tree we obtain the surf browser from the
respective librad project. It imposes in our ways we test and they show
their age now, the testing of the GraphQL API surface should be
reevaluated in due time.

* Attempt to use browser from librad project
* Bump librad
* Nuke test test case
* Bump librad
* Clone platinum per test case
* Fix tags test case
* Fix tests
