Spawn expanding/fading orange explosion effects when enemies or
the player are destroyed. Explosions scale from 15x15 to 50x50
over 0.4s while fading from full opacity to transparent, then
auto-despawn.
Integration points:
- Enemy killed by player bullet (bullet.rs)
- Player hit by enemy bullet (bullet.rs)
- Player collides with enemy (player.rs) - both explode
- Captured player released (player.rs)

This commit introduces a new mechanic where boss enemies can use a tractor beam to capture the player.
Key changes:
- Bosses can now fire a tractor beam that targets the player.
- If the player is caught in the beam for a certain duration, they are "captured".
- Captured players are carried by the boss as it returns to its formation.
- If the boss is destroyed while carrying a player, the player is freed.
- If the player is captured, they lose a life and respawn.
- Refactored player and enemy systems to handle the new capture logic and states.
- Added GEMINI.md and CLAUDE.md to track assistant configurations.
