fix: all loaded chunks now simulate at same tick rate

Browse Source 
- stream_chunks: generate all chunks in radius 2 immediately (was gen_budget=2)
  No more half-generated chunks in active area
- update_active_chunks: activate ALL loaded chunks (was radius 2 around player)
  Physics consistent across all loaded chunks — no frozen boundaries
- streaming radius 3→2 (5x5=25 chunks, all active and simulated)
- 131 FPS surface, 138 FPS caves, p99 17ms
