Updates the `Triangle` class to use a generic `Vector` type instead of `Vector3`, enhancing flexibility and reusability.
Changes include updating relevant function return types to use `Vector::ContainedType` and adapting length and distance calculations accordingly.
This refactoring supports the ongoing work on the EPA algorithm (feature/epa_algorithm) by providing a more adaptable foundation for geometric calculations.
Implements `std::hash` specialization for `omath::Vector2`, `omath::Vector3`, and `omath::Vector4` with float components.
This enables usage of these vector types as keys in hash-based containers, such as `std::unordered_map` and `std::unordered_set`.
Moves linear algebra headers to a new subdirectory to improve project structure.
Updates includes to reflect the directory change.
Adds vcpkg to the tracked repositories.
