Is your feature request related to a problem? Please describe.
Some recent issues have emerged with the EOL certifier introduced in #2215, specifically its failure to produce EOL-related HasMetadata nodes and some CLI issues. Currently, the EOL-on-ingest functionality isn’t validated in our end-to-end tests, making it difficult to prevent regressions or confirm fixes.

Describe the solution you’d like
Following the pattern from #2142, we can enhance the e2e test suite by adding the --add-eol-on-ingest flag. We’d then target a package known to have passed its EOL according to endoflife.date data, ensuring the certifier works as intended in a full integration scenario.

Additional context
Before implementing this, let’s allow recent corrective PRs (#2394 and #2391) to be merged. Once these changes are in, I’ll open a PR to add the e2e coverage and address any lingering issues.
