v0.1.2 update — TradingLife Steam update #1261052

In this update, we are decoupling the maximum leverage from the progression system and introducing a Rank Points system to replace the original maximum leverage system. Any maximum leverage upgrades accumulated in previous versions will be directly converted into Rank Points. The current maximum usable leverage is 10x (we plan to introduce black-market items in future updates to further raise this cap), giving players more granular and consistent risk control.
