Subject: - 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.
