lua-cli-0.0.1 is not a library.
Standalone lua-rs interpreter — minimal entry point that exercises the
full pipeline: new_state → open_libs → load_string → pcall_k.
This is intentionally minimal — its job is to surface which todo!()
stubs block real execution, NOT to be a complete Lua interpreter.
Usage: lua-rs '' Examples: lua-rs 'print("hello")' lua-rs '1+1'
