[quality] generate-cncf-missions.mjs: +15 branch tests (30.56% → 32.93% lines, 40.38% → 45.08% branches)

[hivecommons-hive]

Test Improvement

Adds 15 targeted branch tests for three exported helpers in scripts/generate-cncf-missions.mjs that were under-covered by the existing suites (generate-cncf-missions.test.mjs + .scoring-branches + .format-branches).

What is covered

• buildDescription bug arm — the error:/ERROR:/panic:/FATAL:/failed to: capture group that emits "Users encounter: …", plus the community-reported vs "affects N+ users" suffix split when no error pattern matches.
• buildResolutionSummary — all three arms of the private buildResolutionFallback (pr URL, issue URL, generic), the sourceUrls=undefined guard, and the sentence-truncation happy path that must NOT emit the fallback.
• generateMission end-to-end — top-level kc-mission-v1 document shape, linkedPR presence/absence propagation to metadata.sourceUrls.pr, non-K8s project prerequisites via PROJECT_CLI_MAP (harbor → docker-compose), and the 3-snippet cap on resolution.codeSnippets.

Important

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

This PR's only tracked rationale is #3165, which the hive filed itself — issue #3165 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.
