Add test coverage for CI, mirror, error, event, fennel, and quire modules
Move server.rs from the library into src/bin so it is excluded from
coverage along with the rest of the binary code. Add llvm-tools-preview
to the ramekin Dockerfile so grcov can generate reports in the
container. Extract push_sync from mirror::push for synchronous
testability.

Coverage: 87% → 97%
