Refactor and enhance math, memory, and utilities

Refactored `sincos` usage in `quaternion` to use tuple-based
returns for improved readability. Introduced a `random` struct
with methods for generating random values of various types
and dimensions, including ranges and directions. Added a
`DynamicArray` class for dynamic resizing and manipulation
of collections. Enhanced `SlotMap` with new methods for
safe access and updates.

Updated `uint` vector types with `NumericConvertable`
attributes for better type interoperability. Removed the
`MathUtilities` class and refactored `adj` and `adjInverse`
methods for encapsulation. Improved memory management
with `StackAllocator` and `UnsafeArray` enhancements.

Added geometry utilities like `AABB`, `OBB`, `Plane`, and
`SphereBounds` for 3D operations. Updated project
configuration for versioning and NuGet packaging.
Performed general code cleanup, improved validation, and
aligned with modern C# practices.
