Export DEBIAN_FRONTEND=noninteractive and NEEDRESTART_MODE=a so package installs and service-restart checks never block on an interactive prompt during an unattended setup.

Pull request overview
This PR aims to make the installer reliably headless by preventing apt/dpkg from showing interactive debconf or needrestart prompts that can stall unattended runs (cloud-init/CI/config-management), by setting non-interactive environment variables early in setup.sh.
Changes:
- Export
DEBIAN_FRONTEND=noninteractiveglobally for the installer run. - Export
NEEDRESTART_MODE=aglobally for the installer run.

What
Set
DEBIAN_FRONTEND=noninteractiveandNEEDRESTART_MODE=aat the top ofsetup.shso everyapt-getcall in the installer — and in the sourcedfunctions— runs without prompting.Why
Unattended installs (cloud-init, CI, config-management tooling) can stall when apt or
needrestarttries to open an interactive prompt and there's no TTY to answer it. Setting the non-interactive frontend up front keeps package installation fully headless.Notes
setup.shso they apply beforebootstrap()and propagate to the sourcedfunctions, covering all package installs in one place.
