Improve DPDK installation and CI error reporting#14

The AMI build was failing intermittently on main (3-5min vs 28min for success), likely due to EC2 capacity issues with c5n.large in certain availability zones. Changes: - Switch build instance from c5n.large to m5.large (broadly available, sufficient for DPDK compilation; AMI works on any x86_64 instance) - Add subnet_filter to select default VPC subnets with public IP mapping - Add retry logic (up to 3 attempts with backoff) for transient failures https://claude.ai/code/session_012bWBrKMs2ApjXQfjQebPFs
$GITHUB_STEP_SUMMARY has no REST API for reading (only browser). Annotations ARE readable via gh api .../check-runs/.../annotations, so include the actual Packer error text in ::error:: and ::warning:: annotations. This lets LLM agents diagnose failures without needing to download logs/artifacts. https://claude.ai/code/session_012bWBrKMs2ApjXQfjQebPFs
AL2023 recently moved to kernel 6.12, where the new kernel6.12-headers package conflicts with the legacy kernel-headers (6.1) package. The install script was failing because dnf couldn't install kernel-headers alongside the pre-installed kernel6.12-headers. Fix: make kernel-devel/kernel-headers installation non-fatal since DPDK is built with -Denable_kmods=false (no kernel modules) and the running kernel's headers are already pre-installed. Also improve error annotations to include actual Packer error text, making failures diagnosable via the GitHub API without downloading logs. https://claude.ai/code/session_012bWBrKMs2ApjXQfjQebPFs

Summary
This PR improves the robustness of DPDK installation on Amazon Linux 2023 and enhances error visibility in CI/CD pipelines by providing more detailed failure diagnostics.
Key Changes
DPDK Installation: Modified kernel header installation to handle conflicts on AL2023 with kernel 6.12. Since DPDK is built without kernel modules (
-Denable_kmods=false), the pre-installed headers from the running kernel are sufficient. The installation now gracefully handles the conflict between legacykernel-headers(6.1) and newkernel6.12-headerspackages.CI Error Reporting: Enhanced the Packer build failure error message in GitHub Actions to include:
