Module chunk_sender 

This module is responsible for sending chunks to the client.

Chunk sending runs on its own independent tick loop, separate from the game tick. The three-phase design (prepare → encode → commit) minimizes lock hold time on the per-player ChunkSender mutex so that game-tick operations like mark_chunk_pending_to_send and drop_chunk are never blocked for long.
