Refactors the lightning projectile to handle collisions more effectively. It now stops upon hitting an enemy or object, triggers an explosion, and spawns child projectiles from the collision point. The lightning bolt's collision shape is dynamically updated to match the remaining distance to the target or the collision point. Also adds more test enemies to the map for testing purposes.
Adds an in-game debug menu that displays performance metrics (FPS, frame times) and hardware/software information.
The menu can be toggled using the F3 key (or a custom input binding). It has different display styles, ranging from a compact FPS display to a detailed view with graphs and system information.
