Massive session today. Fixed a blank screen bug that was preventing asteroids from generating on init, then dove deep into the pathfinding system.

Added debug visualization for paths which was essential for debugging. The path finding went through several iterations - fixed external tangent line calculations, corrected arc directions, improved the algorithm with proper tangent points. I extracted a dedicated tangentPathFinder module to keep things clean.

Also added persistence for debug pane values (finally!), set up a commit message validation script, and created slash commands for the dev workflow. Added test cases for the pathfinding edge cases I discovered.

Ships can now transition between asteroids which is a huge milestone!
