Add host-authoritative world-state sync

Implement host-authoritative time/weather sync across server and clients. Adds a new worldState packet (and worldStateHost for host assignment) and server-side host tracking/reassignment to the lowest remaining playerId when the host disconnects. Plugin-side changes introduce F4T::WorldStateSync (new header + implementation), polling/apply hooks in the game-thread main loop, and Networking support to send/receive/parse worldState/worldStateHost packets. The server validates host-only sends, relays worldState to peers, broadcasts worldStateHost on host handoff, and augments logging/stats. Protocol and documentation files updated (protocol/world-state.md, docs/*) and server/fake_client.py extended to track/print host world-state snapshots.
