GuestHeap previously bump-allocated any request >64KiB and never reclaimed it on free() - a real, sustained gameplay session eventually exhausted the arena (traced live to two separate crashes: onCreate never completing, and a NULL-vector dereference in sub_4BA588 caused by a failed ~175KB allocation going unchecked by the real EA code). Widen the existing O(1) size-class free list (already used for <=64KiB requests) to cover the whole arena instead of adding a second reuse mechanism next to it - oversized allocations now pool and reclaim the same way small ones already did. Add matching desktop tests (guest_heap_test.cpp, run via run_heap_tests.sh) covering the exact failing size from the crash log and a sustained alloc/free cycle in an arena too small to survive without reclaim. Verified live on device: the crash is gone across a full 10-minute session with sustained GLES rendering throughout. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
