CLI 0.18.0 — One-command setup and safer automation

The CLI gains guided machine onboarding, classified failures, stable exit codes, grouped help, and safer daemon lifecycle behavior.

Highlights

• mf setup. Sign in, issue a machine token, register the host, install autostart, and wait for daemon health in one command.
• Stable script failures. Network, auth, not-found, invalid-request, and other failures have distinct exit codes and structured JSON errors.
• Safer token input. --token - reads from stdin so secrets do not need to appear in argv.
• Idle daemon auto-update. Official init-managed daemons check every six hours and install only while idle; busy sessions are never interrupted.
• Offline daemon status. A local protected control socket reports daemon version, connectivity, and active sessions without contacting the cloud.
• Bounded logs and strict state. Logs rotate, secret-bearing state writes are atomic, and corrupt configuration fails with an actionable message.
