Pull request overview

This PR restores package building for multiple Linux distributions with important structural changes to the packaging system. It adds support for Debian 13 (trixie), configures EL7-9 packages to use relay-pkg.so binaries, and refactors the package generation to build distribution-specific packages for Debian-based systems.

Key changes:

• Refactored fpm.sh from hardcoded package arrays to dynamic generation using loops over distributions, architectures, and PHP versions
• Added trixie (Debian 13) to supported distributions
• Introduced conditional binary selection (relay.so vs relay-pkg.so) based on distribution

@copilot only define the Debian/Ubuntu list distros once. Avoid the duplicated list.

LGTM but I don't know a ton about packaging.

Nice improvement using a loop for the PHP versions though
