leftibot 96cae78242 Fix #636: Prevent heap-use-after-free in async threads during engine destruction ... The Dispatch_Engine member destruction order destroyed m_state (containing type maps) before m_stack_holder (containing async futures), allowing async threads to access freed type map memory during eval_error formatting. The fix moves async() registration from the stdlib into ChaiScript_Basic with thread tracking, and adds a Dispatch_Engine destructor that joins all tracked async threads before m_state is destroyed.
