Usage:
  drm modules                       list compiled-in app modules and their channels
  drm capture  --app NAME [--channel ID] [--auto-play] [--wvd PATH]
                                    one-shot phone MITM capture
  drm catalog  --app NAME --channel ID [--keys] [--json] [--list]
                                    resolve a channel from its public catalog (no phone)
  drm agent    run|status|devices|enqueue|cancel [--config …]
                                    always-on credential refresher
  drm serve    [--bind …] [--data …] [--token …]
                                    streamd control plane + dashboard
  drm proxy    build|push|install-ca|start|stop|discover|pull|clear-proxy
                                    on-device HTTPS MITM

App modules are compiled in; their local values live in
apps/modules/<name>/module.yaml (gitignored) and can be overridden per run with
--<app>.<field> flags or <APP>_<FIELD> environment variables.

Run any subcommand with --help for its own flags.
