v1.7.0-alpha

knotserver:
* rework Branches and Tags endpoint to use `git for-each-ref`. this is
far more performant that go-git's reference iterator, and it is not
susceptible to the infamous map-write-while-read bug on larger repos.
* emit language breakdown information in gitRefUpdate, this allows
appviews to update their knowledge of a repo language more often.
* improved error handling in knotserver/internal. it should now be
easier to debug failed hooks or pipeline events.
