qli-Service-install-auto.sh hardcodes the x64 package — no architecture detection for ARM64

[Wesley666Wesley]

Problem

The official tutorial "Linux option 2: Run qli-Client as Linux Service (Expert)"
instructs users to download the install script from:

https://dl.qubic.li/cloud-init/qli-Service-install-auto.sh

The script hardcodes the x64 package:

package=qli-Client-3.8.4-Linux-x64.tar.gz

There is no architecture detection (e.g. uname -m), so on ARM64 Linux machines
the script downloads the x64 client, which cannot run. Every user who follows
the official guide on ARM64 hardware hits this wall immediately.

This is unnecessary: official Linux ARM64 packages have existed since 3.8.3
(e.g. qli-Client-3.8.5-Linux-arm64.tar.gz is available on dl.qubic.li).

Suggested fix

Detect the architecture automatically:

ARCH=$(uname -m)
case "$ARCH" in
  x86_64)  package=qli-Client-3.8.5-Linux-x64.tar.gz ;;
  aarch64) package=qli-Client-3.8.5-Linux-arm64.tar.gz ;;
  *)       echo "Unsupported architecture: $ARCH"; exit 1 ;;
esac
