fix: accept omp and copilot in the per-mode command overrides (release review)

RemoteCommandOverridesSchema is .strict() and stopped at deepseek, so the API
refused a commands.omp or commands.copilot override although both modes can run
remotely and in a container (RemoteCommandMode, DockerCommandMode) and the launch
builders honour the key. The docs call the override the way out for a login shell
the stock launch cannot run, which was not true for those two modes.

The test walks the CLI registry, so the next CLI cannot miss the schema the same way.
