[drift] CLI surface changed, consumers need update

Drift Report: Query Template Registry

Affected consumers: ai-baseball-data-analyst (skills/query-data/SKILL.md), scout-app (agent/system-prompt.md)

Finding

bbdata expanded the query template registry from 21 → 22 templates in v0.10.0 (2026-04-21):

• New template added: pitcher-rolling-trend (5-start sliding window for pro-pitcher-eval rolling chart)
• Current count in bbdata: 22 query templates
• Expected by consumers: 21 query templates

Impact

• ai-baseball-data-analyst skills document references "all 21 query templates" but should now reference all 22
• scout-app agent prompt references "all 21 query templates" and needs to list the new pitcher-rolling-trend

Verification

✅ Report templates (13 total) — all expected templates present, no drift
✅ CLI flags (query & report) — all expected flags present, no drift
✅ Audience values (coach, gm, scout, analyst) — all present, no drift
✅ JSON envelope meta fields (source, cached, queryTimeMs, season, sampleSize) — all present, no drift

---

This is a consumer-sync issue, not a bbdata bug. Downstream consumers should update their template references to include pitcher-rolling-trend.
