leftibot c5b81b880f Fix #632: Join async threads before engine destruction to prevent use-after-free
The heap-use-after-free was caused by a race condition where async threads
continued accessing the engine's shared state (global objects map) after the
main thread began destroying the Dispatch_Engine. The fix moves the async
function registration from the stdlib module into ChaiScript_Basic, where it
can track spawned threads via Dispatch_Engine. The engine's destructor now
joins all outstanding async threads before destroying shared data structures.
