// TestDemoRejectsBadFlag verifies demo flag parsing returns usage failure.

// The demo command currently accepts no flags, so malformed arguments must stop
// inside the demo flag set. This keeps the route distinct from the successful
// demo smoke path.
//
// 1. Invoke the command dispatcher with the demo label.
// 2. Pass an unsupported flag to the demo flag set.
// 3. Capture command output.
// 4. Assert the command reports usage status 2.
