POC demonstrating Approach 7 from APPROACHES.md. This commit can be
cleanly reverted with `git revert` if the approach is not adopted.
Changes:
- packages/redis/src/index.ts: Add createWidgetPrefetchCache() factory
that creates a cache channel per widget kind (5min TTL)
- packages/widgets/src/prefetch.ts: Check Redis cache before database
queries. On cache miss, falls back to original DB path and writes
through to Redis for the next request.
Expected behavior:
- First page load: cache miss → DB query → write to Redis (same as before)
- Subsequent loads within 5min: cache hit → skip DB queries entirely
- Redis unavailable: falls back to original behavior (no regression)
- Cache invalidation: automatic via 5-minute TTL
