Implemented fog of war! Used a smoke effect with soft noisy edges that looks great. Added a debug tool for revealing fog and an animation that reveals from the edges. The fog panel has a reset button for testing.

Added a HUD system using Jotai for state management. Asteroids now display their names, and selected ships show in the HUD. Fixed ship selection stroke rendering gaps and clamped keyboard zoom to stay within limits.

Did some deployment fixes - trailing slash redirects, renamed the page title, and switched to relative base paths for assets.
