[quality] cover stackoverflow.mjs final 3 uncovered branches

[hivecommons-hive]

Test Improvement

Adds scripts/__tests__/sources/stackoverflow.final-branches.test.mjs — 3 tests targeting the last uncovered branch arms in scripts/sources/stackoverflow.mjs (96.88% → 100% branch):

• Line 80 FALSE arm — if (items.length < 3): verifies that when the tag search already returns >=3 items, the text-fallback path is skipped entirely (only one fetch call is issued).
• Line 99 TRUE arm — text-fallback if (q.score < this.minVotes) continue: verifies fallback results below minVotes are filtered out.
• Line 100 TRUE arm — text-fallback if (!q.is_answered) continue: verifies unanswered fallback results are filtered out.

Companion to the existing stackoverflow.remaining-branches.test.mjs suite. Tests-only — no production changes.

Important

Held for human sign-off on the direction, not on the code.

This PR's only tracked rationale is #3182, which the hive filed itself — issue #3182 was filed by kubestellar-hive[bot] and no human has acknowledged it. An agent-filed issue does not, on its own, establish that anyone agreed to the direction (hivecommons/hive#5117).

The change may well be right; nothing here is a review of it. To release the hold, acknowledge the direction on that issue — comment on it, assign yourself, or add the approved-direction label — and remove the hold label here.
