Enable full PR matrix for all automatic workflow runs

- Removed conditional logic that limited PR builds to single source

- Now ALWAYS tests all 6 sources (current + 5 PRs) on every run

- Applies to: pull_request, push, schedule, and workflow_dispatch

- Only exception: custom build_sources via workflow_dispatch input

- Provides comprehensive compatibility validation on every trigger
