Spell out the context-manager dunder argument types

Replace *args: Any catch-alls on __exit__ / __aexit__ with the typed
three-argument signature (exc_type, exc_val, exc_tb). The runtime
behaviour is unchanged, but callers and mypy now see the standard
context-manager contract instead of a variadic Any-bag.
