feat(polymarket): add Polymarket prediction markets as 6th research source

Search Polymarket's free Gamma API for relevant prediction markets on any topic. Uses smart multi-query expansion to cast a wider net (e.g., "Arizona Basketball" also searches "Arizona"), merges and dedupes by event ID, and shows price movement context ("up 22.5% this week"). No API key required. Also hides sources with zero results from the stats output (all sources). 54 new tests, all passing. Full pipeline integration with scoring, dedupe, cross-source linking, and rendering. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
