v3.27.1

## Highlights

Patch for the v3.27.0 Grok Bot native X launch, from a smoke test on Grok Bot. (#1237)

- The month's most-engaged on-topic X posts now reach the report. Host-fetched X holds half its slots for its biggest posts that name the topic, so the popular pass's big posts no longer lose to fresher low-engagement ones. Off-topic viral posts never take those slots, and posts from the handles you name are never pushed out.
- The footer's X line now says where X came from: "via Grok Bot X" or "via X connector".
- The Grok Bot X recipe gives discovered authors only topic-word searches and uses the engine's UTC date for the window.

Update: `grok plugin update last30days`, `claude plugin update last30days`, or re-run `npx skills add mvanhorn/last30days-skill -g -y`.
