Install MAMA OS

1. Install the local server:

   npm i -g @jungjaehoon/mama-os

2. Read the current installation contract:

   mama --help

3. Run the machine-readable observer and follow only the actions it reports:

   mama status --json

Repeat mama status --json after each state change. Ask the human only for actions identified by
the status output as human-required. Do not infer success from installed files or a running daemon;
the installation is complete only when the returned onboarding state says complete: true.
