Move broadcast message parsing logic from profiler/src/main.cpp into server/TracyBroadcast.cpp/hpp. This reduces code duplication and enables reuse by other tools (e.g., multi-capture). ParseBroadcastMessage() handles all broadcast protocol versions (0-3) and returns std::optional<BroadcastMessage>. ClientUniqueID() generates a unique identifier from IP address and port.
