Revamped Volume, OI & Smart Money

Rebuilt how we calculate volume, open interest, and smart money signals from the ground up. Both Polymarket and Kalshi markets now pull data directly from each exchange's API, so the numbers you see in the sidebar and on market pages are accurate and consistent. Open interest is now visible on every market page. The smart money algorithm now uses live trader grades instead of historical snapshots, and we added a minimum threshold so only meaningful positions show up as signals.
