Backend: AgentRegistryService gains findByApplicationAndEnvironment() and environment-aware addGroupCommandWithReplies() overload. AgentCommandController and ApplicationConfigController accept optional environment query parameter. When set, commands only target agents in that environment. Backward compatible — null means all environments. Frontend: All command mutations (config update, route control, traced processors, tap config, route recording) now pass selectedEnv to the backend via query parameter. Prevents cross-environment command leakage — e.g., updating config for prod no longer pushes to dev agents. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
