Pull request overview

This PR updates the Debian 10 and 11 builder scripts so that Debian packages are built for the builder’s native architecture instead of being hardcoded to amd64.

Changes:

• Introduces an ARCH variable derived from dpkg --print-architecture and uses it in the generated .deb filename.
• Updates dependency extraction to attempt to strip the architecture suffix dynamically instead of assuming :amd64.
• Cleans up and corrects some apt-get install lines and comments in the builder scripts.
