* checkpoint sync use finalized state+block instead of finding the block at the beginning of the weak subjectivity epoch. * happy path test for sync-from-finalized * gofmt * functional opts for the minimal e2e * add TestCheckpointSync option * wip: pushing for CI * include conn index in log for debugging * lint * block until regular sync test finishes * restore TestSync->testDoppelGangerProtection link * update bazel deps for all the test targets * updating to match current checksum from github Co-authored-by: Kasey Kirkham <kasey@users.noreply.github.com>
