- The premake5.lua file has been updated to include the LUA_COMPAT_BITLIB compiler definition. This flag instructs the compat-5.3 submodule to build the actual bit32 library instead of a stub that throws a deprecated error.

- The main function in src/lush.c is modified to explicitly load the bit32 and utf8 libraries into the global Lua state at startup using luaL_requiref. This makes them directly accessible to all scripts running in the shell, which is necessary for the test script to find and use the bit32 functions without a require() call.
- Added a null check after luaL_newstate() in src/lush.c to ensure the Lua state is created successfully before its actually used.
