feat: add scrolling starfield background

Browse source 
Add 150 stars with randomized positions, sizes, speeds, and brightness.
Stars scroll downward with parallax depth effect and wrap around at
screen edges. Also fixes Bevy 0.13 API issues in game_state.rs
(KeyCode::R → KeyR, Input → ButtonInput).
