docs(readme): replace process substitution with pipe syntax in install commands

Browse Source 
- swap `sudo bash <(curl …)` for `curl … | sudo bash -s -- setup` to fix `/dev/fd/63` errors under sudo
- add callout explaining why process substitution fails with `sudo bash`
- update one-shot command to `curl … | bash` and clarify auto-elevation behavior
- fix version-reporting note to reflect pipe mode instead of process substitution
