Found while testing onctl -p ac without Apple's container CLI: the message was right, but

• onctl -p ac claude printed it twice -- cobra's Error: plus the whole usage text, as if it were a typo, then main's log line -- and exited 0;
• onctl -p ac ls logged it, printed an empty table and exited 0, so a script read "no VMs".

The cause is general, not ac's: main logged Execute's error and returned, and ls never returned one.

Changes:

• main.go: os.Exit(1) after logging the error.
• rootCmd: SilenceUsage and SilenceErrors, so a run-time failure is main's one line. A bad flag keeps a pointer to the usage through flagError: unknown flag: --kep / Run 'onctl claude --help' for usage.
• ls: RunE, returning the provider's error after printing what the other call did return (as listVMs intends).

Checked by hand with the CLI path pointed at a missing binary: claude and ls exit 1 with one error line, an unknown flag exits 1 with the hint, a working ls still exits 0. Tests: TestListCmd_ProviderErrorIsTheResult, TestRootErrorsPrintOnce.
