test: Gather and upload CI logs (#30)

<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->

## Summary by CodeRabbit

* **Chores**
* Continuous Integration now captures and uploads build/test logs and
system information as downloadable artifacts after each run.
* Artifacts include service logs and integration test outputs, aiding
post-run analysis and issue triage.
* Logs are retained for 7 days and are available even when jobs fail,
ensuring consistent access to diagnostic information.
