[Optimizations & Adjustments]
1. Added a new redeemable item, Degenerate Shell, to the Light Contract - Contract Store.
2. Optimized the usage logic of speedup items: When using "Auto Heal" & "Quick Speedup" & "Speedup Items," if the excess speedup time exceeds 1 minute, the overflow will be returned to the Inventory in the form of 1-min speedup items of the corresponding type.
