- Add useTagSparklines hook that queries kind-1 posts for each trending tag over the last 24 hours, buckets them into 10 time intervals, and returns actual post counts per bucket. - All tags are fetched in a single relay query for efficiency. - TrendSparkline component now accepts a `data: number[]` prop and renders the real activity curve instead of random noise. - Remove all seeded PRNG code that was generating fake trend lines.
