Replaced the deprecated Allocator API with the new AllocationHandle API across the codebase. Updated constructors, methods, and tests to use AllocationHandle for memory management. Marked Allocator-based methods as [Obsolete] and provided alternatives.
Added OwnershipTransferAnalyzer to detect ownership transfer issues and introduced OwnershipTransferAttribute for marking parameters. Enhanced DefensiveCopyAnalyzer with additional checks for readonly and ValueType instances.
Refactored internal memory management in AllocationManager and updated benchmarks, utilities, and documentation to reflect the changes.
BREAKING CHANGE: Deprecated Allocator API in favor of AllocationHandle. Updated constructors and methods to use AllocationHandle. Users must migrate to the new API.
Refactor memory allocation system to use generic MemoryPool<TAllocator, TOpts> for arena, stack, and free list allocators, replacing custom allocator structs. Introduce MemoryBlock as a safer, more robust replacement for UnTypedArray. Improve thread safety, safety checks, and documentation. Reorder and clarify Allocator enum. Add comprehensive unit tests for all allocators and pointer assertion utilities. Update project to enable safety checks in Debug builds. Remove obsolete interfaces and ensure consistent deallocation with MemoryUtility.Free.
BREAKING CHANGE: Custom allocator structs are removed and replaced with MemoryPool-based abstraction. UnTypedArray is replaced by MemoryBlock. Allocator enum order and semantics are changed. Public API changes may require code updates.
