Installing Taubyte Tooling

When to use

First-time machine setup for tau / dream
tau --version / dream --help fails
docker info fails or docker is missing
npm i -g @taubyte/cli was attempted but didn't produce a working tau
A new shell session and you don't know whether the toolchain is in place
Hard gate before every other Taubyte skill (run this first if anything below seems off)

Situation	Action
Node missing AND can't be installed from this environment	Stop; give OS-specific install instructions; do not run `npm i -g` until `node`/`npm` work.
Docker CLI missing AND daemon can't be started	Stop before Dream / `dream inject` / any container-backed flow.
`tau` or `dream` still broken after install attempts	Stop; record what was tried and the failure output.
GitHub-backed work needed but no `tau` profile	Stop; defer to authenticating-taubyte-cli.
