Navigation mesh

The navigation mesh, or navmesh for short, is used by AI entities such as bots, robots and bosses to find their way around the map. Trying to use the entities without a navmesh will lead to them not working.

The navmesh is composed of a set of areas that define the accessible areas of the map and their properties. The areas are linked with directional edges to track which areas are reachable from each other.

A basic navmesh can be generated automatically using the console command `nav_generate` but manual adjustments are likely needed.
