Handles special addresses (Assistance Fund 0xFE, HIP-2 0xFF) that don't emit order_status events by creating synthetic Alo Limit order entries. Removes the spot coin subscription filter. Opt-in via --include-spot-unsafe CLI flag since the order type assumption is an approximation. Cherry-picked from hyperliquid-dex#10. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

It seems like the reason spot is not currently supported is because special addresses (HIP-2 & Assistance fund) do not produce order_status events and the order book state panics when a diff with no matching order_status is found.
This solution assumes all orders from HIP-2 & Assistance fund are Alo Limit orders without a trigger price/condition. (which I believe is always the case?)
