Authenticating Taubyte CLI

When to use

• First-time tau setup on a machine
• tau returns GET -- \/me` failed with status: 401 Unauthorized`
• tau new project or tau import fails citing GitHub auth
• Need to retrieve the GitHub token for direct HTTP calls (jobs API, repository registration)

Mental model

tau stores profiles in ~/tau.yaml. Each profile holds a GitHub token used to call both the cloud API and GitHub itself. There are two ways to get a token into a profile:

1. Token-based login (preferred for automation): supply an existing GitHub PAT.
2. Browser OAuth (tau login --new): the CLI starts a local callback server, prints a URL, and you finish authorization in the browser.

Token-based login (preferred)
