Add Lua scripting support to desktop emulator

- Created emulator-specific lua_game_emulator.cpp using filesystem instead of FatFS
- Created lua_game_loader_emulator.cpp to scan games/lua_examples directory
- Updated CMakeLists.txt to include Lua 5.4 engine and bindings
- Updated to SFML 3.0 API compatibility (event handling, sprite initialization)
- Updated Game class to use public members for Lua bindings
- Updated GameLauncher to use std::function for lambda captures
- Added continuous 60 FPS rendering for smooth display
- Emulator now loads and runs all three example Lua games
