Replace POSIX-specific socket and process APIs with portable abstractions so the project builds on both Windows and Linux. - Add include/network/net_platform.hpp: Winsock2/POSIX socket abstraction (socket types, non-blocking, error handling, WSAStartup lifecycle) - Add include/platform/process.hpp: CreateProcess/fork+exec abstraction for spawning ffplay subprocesses - Update network module (tcp_socket, world_socket) to use portable socket helpers instead of raw POSIX calls - Update audio module (music_manager, footstep_manager, activity_sound_manager) to use portable process helpers instead of fork/exec/kill/waitpid - Replace hardcoded /tmp/ paths with std::filesystem::temp_directory_path() - Link ws2_32 and SDL2main on Windows in CMakeLists.txt
