Updates the include paths in omath.hpp to be more explicit,
ensuring correct referencing of header files.
Removes unnecessary include of vector3.hpp from vector2.hpp.
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.
Creates the main omath header file that includes all
omath library components. This provides a single point
of inclusion for the entire library, simplifying usage
and dependency management.
Also, adjusts the return types for projectile prediction
functions within the legacy engine to explicitly use
the `Vector3` type for consistency and clarity.
