[Docs]: Quick-start examples missing required auth setup

[bcdady]

Issue Summary

The quick-start examples in both the main README and packages/server/README.md show:

npx @neuralnomads/codenomad --launch

Running this without a password immediately crashes with:

[ERROR] [app] CLI server crashed err=Error: No server password configured.
Create /home/<user>/.config/codenomad/auth.json or start with --password / CODENOMAD_SERVER_PASSWORD.

Suggestions

1. Update quick-start examples to include --password or mention that auth setup is required before first run.
2. Document the auth.json file format. The error message tells users to create ~/.config/codenomad/auth.json, but neither README describes its expected schema.

Environment

• OS: Ubuntu 24.04 (Linux)
• Node: v22 via mise
• Ran via: npx @neuralnomads/codenomad
