⚡ Bolt: Hoist state allocation out of tickDiskAutoFill Pass 3 hot loop - #992

Conversation
💡 **What**: Hoisted the `checkState` object creation outside the `flushSizes` loop in `tickDiskAutoFill` Pass 3.
🎯 **Why**: In `tickDiskAutoFill`, Pass 3 contained a loop evaluating `isDiskRedeemable`. It passed an inline deeply-spread object `{ ...state, intro: { ...state.intro, poolBuffers, disks, diskCache, diskReadCacheFlush } }` on *every iteration*. Allocating this heavy nested object entirely anew on every single iteration caused extreme memory allocations and garbage collection thrashing during large batch processes (like calculating massive offline progress).
📊 **Impact**: Turns an O(N) memory allocation and GC pressure spike into an O(1) cost. Because `poolBuffers`, `disks`, `diskCache`, and `diskReadCacheFlush` are captured by reference, mutations within the loop are still correctly reflected in `checkState` without needing reallocation.
🔬 **Measurement**: Noticeable reduction in thread lockups when simulating massive offline progress.
