Summary

The current docs still reference outdated commands such as nemoclaw setup and nemoclaw connect, and prerequisites are scattered across multiple files.

Problem

New users hit immediate command failures or miss environment setup steps because the rendered docs are inconsistent with the current CLI.

Expected behavior

The quickstart should reflect the current command surface and point users to a single prerequisite checklist.

Acceptance criteria

• Replace deprecated commands in all rendered docs.
• Add one prerequisite checklist covering Node.js, npm, Docker, OpenShell CLI, and any current Linux-specific requirements.
• Add a troubleshooting page linked directly from the quickstart.
• Add doc checks or tests that catch command drift between code and docs.
