* Keep escaped generator frames and wrap asyncgen throw
Mark gi_frame/cr_frame/ag_frame as escaped so locals survive
deallocation, and let frame.clear() drop those locals after
owner finalize. Route throw() through finalize_send_result so
StopAsyncIteration is wrapped like send(). Add ag_suspended
and drop never-started frame locals on close().

* Store escaped on iframe; skip unused cold alloc
Keep the escaped flag on InterpreterFrame so mark_escaped
and has_escaped do not allocate FrameColdData. Clear optional
cold fields only when they exist. Transfer frame owner in
close() the same way send/throw already do.

* Replace escaped flag with take_ownership
gi_frame returns the frame object. Close uses a uniquely-referenced
check to clear locals or take_ownership onto a husk. frame.clear()
finalizes a generator-owned frame and only clears FRAME_OBJECT
frames. close() leaves the generator suspended when it yields on
GeneratorExit.

* Drop frame mutex; steal frame_obj atomically
take_ownership stores None in an atomic slot instead of locking
and swapping a husk. gi_code reads the kept executable. Resume
exclusivity stays on the running claim.
