⚡ Bolt: Reuse GameStateSchema in broadcasts

💡 What: Optimized broadcast_filtered_states to calculate the full game state schema once and reuse it when generating player-specific views.
🎯 Why: To prevent redundant O(N) serialization of the full game state for every player (O(N) total overhead) during broadcasts.
📊 Impact: Reduces Pydantic model creation overhead by factor of N (where N is player count) during state broadcasts.
🔬 Measurement: Verified with pytest and a reproduction test case for mutation safety.


PR created automatically by Jules for task 8766074269812759257 started by @WeixuanZ

Reduces redundant serialization by computing the full GameStateSchema once
and passing it to player-specific view generation, instead of re-serializing
for every player.

Addresses a mutation bug where modifying the reused schema in-place caused
side effects; now uses model_copy() to ensure safety.
