Changelog: Multi-Market Detection

We have rebuilt how CSPump detects pumps. Instead of watching a single marketplace and confirming against Steam, we now track five independent markets and treat cross-market agreement as the core signal. One market moving can be a single seller. Several moving at once is much harder to fake.

What's New:

• Five Market Groups: YouPin, C5, Buff, Steam, and CSFloat are each measured against their own price history. A pump requires at least two of them to agree, and at least one has to be a market you can actually trade on.
• Chinese Market Lead Detection: When the Chinese markets reprice and Steam has not followed yet, we flag it as accumulation rather than a pump. This is the earliest warning we can give, often before the move reaches the Western market.
• Markets Moved: Accumulation alerts and cards now show which markets had moved when we flagged the item, and by how much. If a skin is up 128% on Buff while Steam is flat, you see that directly.

Under the hood, price data now comes from six marketplaces, and all verification runs on our own historical data rather than a third-party feed. That means faster detection, more accurate pricing, and no single point of failure.
