docs(readme): Update setup instructions to use sudo pipes

The installation instructions in the README have been updated to pipe the `curl` output directly into `sudo bash`.

As we now mandate root privileges on setup, the standard `bash <(curl...)` command fails when prepended with `sudo` due to process substitution permissions. This fix ensures all new Commanders can deploy their Sentinels flawlessly on the first attempt.
