- Add stdlib/io.c with PrintLine, Print, PrintInt, PrintFloat, PrintBool, ReadLine - Support extern function declarations (functions without body) - Generate C forward declarations for extern functions - Map Bux type names (String, int, etc.) to C types in codegen - Update build system to copy all stdlib files - Hello World example works: prints 'Hello, Bux!'
