Summary

New modules: Threading, Heapq, Traceback — typed bindings for Python's threading, heapq, and traceback standard library modules
Extended Builtins: Added getattr, setattr, hasattr, isinstance, type to IExports interface with convenience wrapper functions
Extended Queue: Added get_nowait() to Queue and SimpleQueue, plus Empty and Full exception types

This allows downstream projects (e.g. Factor) to use these bindings directly instead of creating their own FFI wrappers.

Test plan

All 262 tests pass (just test-python)
New tests for all added modules: TestThreading, TestHeapq, TestQueue, TestTraceback, TestBuiltinsAttr

          feat: Add threading, heapq, traceback bindings and extend builtins/queue

823516d

Add new stdlib bindings so downstream projects don't need to create
their own FFI wrappers for common Python modules.

New modules:
- Threading: Thread, Lock, RLock, Event classes + module functions
- Heapq: heap operations (heappush, heappop, heapify, nlargest, etc.)
- Traceback: print_exc, format_exc, print_stack, format_stack

Extended existing modules:
- Builtins: getattr, setattr, hasattr, isinstance, type
- Queue: get_nowait(), Empty and Full exceptions
