# GAL-55: Add a "Press R to Restart" message to the `GameOver` screen and implement restart logic

Add a "Press R to Restart" message to the `GameOver` screen and implement restart logic.

## Acceptance criteria

- [ ] "Press R to Restart" rendered as part of `GameOverUI` (`RestartMessage` component already exists in `components.rs`).
- [ ] Pressing R while in `GameState::GameOver` transitions back to `GameState::Playing`.
- [ ] On restart, these reset to defaults: `Score`, `PlayerLives`, `CurrentStage`, `FormationState`, `AttackDiveTimer`, `EnemySpawnTimer`, `RestartPressed`.
- [ ] On restart, all `Enemy`, `Bullet`, `EnemyBullet`, `Explosion`, and `TractorBeam` entities are despawned.
- [ ] Player respawns at default position with invincibility window.
- [ ] R is ignored in `Playing` and `StartMenu` states.

## Integration test hints

- Build `App` in `GameOver`; insert a fake `Score = 1234`, `CurrentStage = 4`; simulate `KeyCode::KeyR` press via `ButtonInput<KeyCode>`; tick; assert state is `Playing` and resources reset.
- Pre-spawn enemies/bullets/explosions before restart; after restart tick, assert their entity counts are zero.
- Negative test: send `KeyR` while in `Playing`; assert no resource reset and no state change.
