fix(eng-analytics): report product test spans

[rnegron]

Problem

• Product-test JUnit artifacts use a separate prefix, so the timing reporter never downloads them and Engineering Analytics receives no product-test spans.

Loading

• Download both existing artifact prefixes without renaming producers.
• Reconstruct repository-relative product paths before span naming, selectors, and ownership lookup.
• Keep missing artifacts and telemetry best effort.

How did you test this code?

• Reporter tests: 41 passed. The new case catches product-relative paths losing ownership context.
• Workflow lint, actionlint, Ruff, and CI preflight passed.

Autonomy: Human-driven (agent-assisted)

• Codex implemented this as an independent prerequisite fix. Skills: wt, authoring-ci-workflows, writing-tests.
• The existing artifact contract remains compatible with open PRs and the Trunk-removal PR.

Note

🤖 stamphog reviewed 32d5b0be57c493ca34dd4a4c756cd239fb2c2033 — verdict: REFUSED

Gates denied this PR (CI/deploy workflow changes hit the infra_cicd deny-list and the change is classified T2-never), so it requires human review regardless of diff quality; the change itself looks reasonable and the earlier Greptile P1 concern appears fixed, but policy doesn't allow auto-approval past a denied gate.

• 👍 on the PR from greptile-apps[bot], hex-security-app[bot].
• Gate verdict DENIED: deny-list match on infra_cicd (CI workflow changes to .github/workflows/ci-backend.yml and .depot/workflows/ci-backend.yml)
• Tier classified as T2-never, which requires human sign-off by policy

.github/workflows/ci-backend.yml:3571
**Product artifact metadata is misparsed**

When this pattern adds `product-junit-results-<index>` directories to the reporter, its parser only removes a leading `junit-results-` prefix, so product spans receive the incorrect suite and segment `product-junit-results`, causing misleading trace names and trace keys.
