Expand description

Derives a deterministic [TradeId] for a Polymarket market data trade.

Polymarket does not publish a trade ID with last_trade_price events, so one is derived from the trade’s identifying fields. FNV-1a is stable across architectures and crate versions, and the 0x1f delimiter prevents variable-length fields from colliding (e.g. "0.12" + "34" vs "0.1" + "234").
