/**
* @file Tests for server/lib/lane-sync.js against a REAL git fixture: a bare
* "origin", a lane clone, and a second clone acting as another lane that
* pushes to origin/development independently. Mirrors the fixture shape of
* Shipyard's own lane-sync-dev.sh test (test_sync_dev.sh) — collision
* detection, clean merges, and conflicts are git's own behavior, so a mocked
* git would only test our idea of git.
