I've made some improvements to address stack overflow issues and enhance memory management.

Key Changes:

• Increased Stack Size:
  The stack size has been increased to 2048 bytes for overflow_stack and 8192 bytes for allocate_stack_with_increased_size to prevent stack overflow errors. These values can be adjusted as per your system requirements.

• Replaced Array with Vec:
  The static array in overflow_stack has been replaced with a dynamic Vec<u32>, which allocates memory on the heap, eliminating the risk of stack overflow.

• Memory Management in overflow_heap:
  I introduced a variable to track the allocated memory in overflow_heap. Additionally, I added an exit condition when the total allocated memory exceeds 100MB to prevent infinite memory allocation.

• Optimized memory_size Attribute:
  The memory_size attribute in #[jolt::provable(memory_size = 8192)] has been updated to 8MB, allowing the function to handle larger memory sizes, which is particularly useful when allocating multiple vectors.

These changes should resolve the stack overflow and memory issues, improving stability.
