feat: Implement boss tractor beam and player capture

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.
