feat: port checks and domains :report subcommands to golang

The bash :report implementations for the checks and domains plugins are replaced with a compiled golang binary that collects report keys in parallel and marshals json directly. The domains global report header now matches the shared renderer used by every other golang report, and its bats assertion is updated accordingly.
