s&box PlayerData Pattern: Persistent Stats with Auto-Respawn

Managing persistent player data across sessions in s&box requires a pattern that survives player character death and handles respawn timing. Common challenges include:

1. Separating player data from the player character GameObject
2. Persisting stats (kills, deaths) across respawns
3. Handling automatic respawn timing
4. Managing the relationship between Connection, PlayerData, and Player components
