Introduce a unified Reallocate method to all memory allocator types (Arena, Stack, FreeList, VirtualArena, VirtualStack, DynamicArena) and require it in the IMemoryAllocator interface. This enables efficient resizing of memory blocks, with fast-path optimizations for stack-like allocators.
Update AllocationManager and MemoryPool to use the new Reallocate method, simplifying and optimizing memory resizing logic. Add public properties for buffer pointers, sizes, and offsets to allocator structs for easier diagnostics.
Set FreeList's default concurrency level to 1 and make its allocation method return null on dispose instead of throwing. Clean up vector types for formatting, fix UnsafeList's RemoveRangeSwapBack logic, and simplify RemoveAtSwapBack.
Simplify Program.cs to only run SPMDBenchmark. Add new unit tests for FixedString, UnsafeList, UnsafeHashMap, and UnsafeHashSet. Apply minor test code cleanups for consistency in TestUnsafeQueue.
BREAKING CHANGE: IMemoryAllocator now requires a Reallocate method, and allocator APIs have changed accordingly.

Add AllocationManager.GetTotalAllocatedMemory() to track total allocations when safety checks are enabled. Improve diagnostics by calling Debug.Fail in Dispose methods of HashMapHelper, UnTypedArray, and UnsafeArray when disposing uninitialized or already disposed arrays. Remove AddRange(ReadOnlyUnsafeCollection<T>) from UnsafeList<T>. Increment assembly version to 1.6.4. Ensure arrcpy is disposed in Program.cs.

Remove FreeList allocator in JobSchedular and debug-layer code, simplifying memory management. Improve memory leak detection and reporting, update memory allocation API, and guard all safety/debug features with new defines. Update csproj files, README, and code samples to match new API and toggles. Fix and improve collection types for correct behavior with and without safety checks. The codebase is now more modular and easier to configure for different build environments.
BREAKING CHANGE: Old defines (ENABLE_SAFETY_CHECKS, ENABLE_DEBUG_LAYER, ENABLE_MIMALLOC) are replaced with MHP_* equivalents. FreeList allocator and related debug features are removed. Some APIs and behaviors have changed for safety/debug configuration.
CopyTo, CopyFrom, ToArray, and ToList are now implemented as instance methods on UnsafeArray<T> and UnsafeList<T>, replacing the previous extension methods. This change enables more direct and efficient copying between unsafe collections and managed spans, arrays, and lists, with overloads for ranges and resizing as needed. Extension methods for these operations have been removed. Minor cleanup and usage updates are included.
BREAKING CHANGE: Extension methods for copying and converting between unsafe collections and spans/arrays/lists have been removed. Use the new instance methods instead.
Adds a debug layer for memory allocation tracking, enabled in DEBUG builds via ENABLE_DEBUG_LAYER. When active, allocations and reallocations in FreeListAllocator store stack traces and maintain linked lists of allocation headers for enhanced debugging. Memory is optionally cleared on allocation, and debug metadata is properly cleaned up on free. Updates allocation logic to support debug and non-debug modes. Also updates AssemblyVersion to 1.5.4 and revises Program.cs to use the new allocation manager initialization and FreeList allocator.

Introduced MemoryPool<T, TOpts> for allocator lifetime management and AllocationHandle access. Updated Program.cs to use MemoryPool, replacing AllocationManager. Minor project file updates included.
Introduce VirtualArena for large, thread-safe virtual memory allocation and FreeList allocator for efficient persistent allocations. Update AllocationManager to support new allocators, add cross-platform virtual memory utilities, and improve thread-safety and performance in existing allocators. Bump version to 1.5.0 and update project configuration.
BREAKING CHANGE: AllocationManager initialization now requires explicit parameters for arena and FreeList capacities. Existing allocator usage may require code changes.
Major breaking change: job interfaces now use JobExecutionContext
instead of threadIndex, enabling thread-aware and dynamic job
dispatching. Updated all job system, SPMD, and test code to match.
