259ff36100 Improve FreeList/TLSF allocators: alignment, GC, decommit
- FreeList: enforce min 16B alignment, use GCHandle for SharedState lifetime, switch to AllocZeroed, and use MemoryUtility for oversized allocs
- Add FreeList.CollectLocal() to flush thread-local caches
- TLSF: add decommitted flag, support front splitting for alignment, add Collect() to decommit large free blocks, use Munmap for cleanup
- Add VirtualMemoryBlock for virtual memory management
- Add tests for CollectLocal (FreeList) and Collect (TLSF)
- Update default allocator config and minor .csproj cleanup

d2c165bbe5 Centralize memory ops via MemoryUtility, add VM support
Refactor all memory allocation/deallocation to use MemoryUtility, replacing direct calls with unified methods. Introduce cross-platform virtual memory management (Mmap, Munmap, Decommit, Recommit). Switch to NativeMemory for standard allocations. Enhance FreeList with global free buckets and thread safety. Standardize alignment/size calculations. Remove global usings for memory utils. Bump version to 1.6.24. Includes minor cleanups and improved docs.

f8b11182a9 Refactor allocation flags, SPMD API, and cleanup
Replaced HasFlag with HasOption for allocation flags to avoid boxing and improve performance. Added AllocationOptionExtensions. Reduced FreeListChunkSize default. Removed redundant allocation handle checks. Renamed MultipleAdd to MultiplyAdd in SPMD interfaces and implementations, updating all usages. Expanded SPMD lane interface with new mask/scatter methods and XML docs. Updated GGX jobs and allocation tests. Bumped assembly versions.

d3e497c7d8 Add TLSF allocator and refactor allocation API
- Introduced TLSF allocator with thread-safe wrapper and integrated into AllocationManager.
- Extended AllocationManagerDesc for TLSF config; made properties settable.
- Refactored AllocationHandle to encapsulate function pointers and state, replacing direct field access with methods.
- Updated all memory-related structs to use new AllocationHandle API.
- Added ReplaceIfZeros utility to MemoryUtility.
- Improved IndexOfNullByte performance.
- Minor fix in MemoryLeakException output order.
- FreeList now uses a fixed 64KB refill budget.
- Bumped version to 1.6.21; removed MHP_ENABLE_STACKTRACE from Debug.
- Updated Program.cs to test TLSF allocator and manage allocation lifecycle.

155d7b0fbd SPMD API overhaul: gather/scatter, job & packaging updates
- ISPMDLane: add MaskGather, MaskStore, Scatter, MaskScatter; update MaskLoad/Gather signatures for hardware parity
- WideLane/ScalarLane: implement new methods with HW/fallback logic
- MathV: gather/mask-gather now delegate to lane methods
- Vector2/3/4: add CompressStore, Scatter, MaskScatter
- SPMD jobs/tests/README: migrate to new APIs for correctness
- Use Unsafe.BitCast instead of Unsafe.As/AsRef
- Add SPMDUtility for gather index extraction
- Job system: add ICustomJob<TSelf>, ScheduleCustom overload
- FreeList concurrency obsolete; always thread-safe
- NuGet: include LICENSE/README, set license/readme in .csproj
- Docs: update SPMD usage, clarify safety notes
- Minor: doc fixes, CompressStore test improvements

a0deadc363 feat(memory): refactor allocation and add new queue
Refactored memory management by removing safety checks and introducing `MemoryHandle` for centralized tracking. Simplified allocation logic across allocators and enhanced `Dispose` methods for better resource cleanup.

Added `UnsafeChunkedQueue<T>`, a lock-free, dynamically resizing queue with chunk-based memory management, supporting parallel producers and consumers.

Updated unit tests to validate new queue functionality and ensure compatibility with refactored memory logic. Incremented assembly version to 1.6.12.

BREAKING CHANGE: Removed `#if MHP_ENABLE_SAFETY_CHECKS` blocks, altering memory validation behavior.

9824c1ed19 feat(buffer): add TLSF allocator and seqlock primitives
Added a TLSF (Two-Level Segregated Fit) memory allocator with O(1) allocation, free, and reallocation in `TLSF.cs`, plus comprehensive unit tests. Introduced a cache-line-padded `SeqLock` synchronization primitive. Refactored vector extension code for conciseness and fixed its usage to `extension(ref ...)`. Updated namespaces, removed unused code, and improved assertion and diagnostics. Updated NuGet dependencies and project files.
