Misaki 69b054e81d feat(lowlevel): add VirtualStack, update allocators, docs

Introduce VirtualStack allocator, refactor memory management to use virtual memory stacks, and update documentation.

Added VirtualStack as a new stack allocator using virtual memory, replaced Stack with VirtualStack in allocation manager and related APIs, and updated TempJobAllocator to use VirtualArena. Introduced AllocationManagerInitOpts for allocator configuration. Replaced ENABLE_COLLECTION_CHECKS with ENABLE_SAFETY_CHECKS for safety checks. Removed Result.cs and updated project files and examples. Added comprehensive README files for all major packages and improved root documentation.

BREAKING CHANGE: Stack allocator replaced by VirtualStack; TempJobAllocator and AllocationManager initialization signatures changed; Result types removed.

Misaki.HighPerformance.Mathematics

Math helpers, geometry primitives, numeric types, and SIMD-friendly utilities for performance-sensitive C# code.

This package focuses on fast scalar and vector math while keeping the API surface practical for game, simulation, rendering, and systems work.

What it includes

common math constants and helpers
custom numeric types
quaternion and random helpers
geometry primitives
SIMD-oriented vector utilities
generated vector extensions and codegen-backed math support

Highlights

constants exposed for float and double workflows
System.Runtime.Intrinsics-based helper code
geometry types for bounds and spatial calculations
designed to support vectorized and low-overhead numerical code

Main types

math
quaternion
random
svd
float
double
int
uint
bool
AABB
OBB
Plane
SphereBounds

Example

using Misaki.HighPerformance.Mathematics;

float radians = math.radians(90f);
float degrees = math.degrees(radians);
float tau = math.TAU;

Package reference

dotnet add package Misaki.HighPerformance.Mathematics

Notes

This project targets net10.0, enables unsafe code, and uses generated source for parts of its vector API surface.
