fix(main): Ensure Lua configuration is loaded on startup. This commit adds the necessary call to core.lua_api()->load_init_file() in main.cpp. This ensures that both the embedded default Lua configuration and the user's init.lua are loaded when Lumacs starts. This change was inadvertently left uncommitted from a previous task that addressed Lua initialization issues.
