Adds passthrough() helper with DisableFlagParsing=true so commands
that do their own flag.FlagSet parsing receive flags directly.
Without this, cobra rejects unknown flags like --model.
Also runs go mod tidy — core/go transitively pulls in cobra and
charmbracelet dependencies.

Inspired by BugSETI architecture — system tray with WebView2 windows,
Docker Compose stack (Forgejo + InfluxDB + inference proxy), and
scoring agent integration. Builds as signed native binary on macOS.
