- Added `Sandbox.Players`: a synchronized list of `NetworkPlayerId` structs representing connected players.
- Added `Sandbox.Events.OnPlayerJoined` and `Sandbox.Events.OnPlayerLeft` callbacks, synchronized across all clients.
- Changed internal interpolation of quaternions to use `Slerp` instead of `Lerp`.
- Fixed a potential crash caused by undefined behavior when reaching `NetickConfig.MaxPlayers` and destroying network objects.
