Update `symtable` from 3.14.2

- Fix from_windows_err using new_exception_empty on OSError subclasses
  (ConnectionRefusedError, ConnectionAbortedError), which caused segfault
  in release builds due to debug_assert on type size mismatch
- Move ConnectPipe from instance method to module-level function
- Add Destructor for Overlapped to cancel pending I/O on object cleanup
- Add NMPWAIT_NOWAIT, NMPWAIT_USE_DEFAULT_WAIT, NMPWAIT_WAIT_FOREVER
  constants to _winapi

* Simplify upgrade-pylib.md by removing manual copy steps handled by quick command

* Let upgrade-pylib run auto-mark instead marking manually

* Let upgrade-pylib a separate commit from updating module

* Correct commands' permissions

* Add open PR check to upgrade-pylib-next command

* Fix dependency pattern example in upgrade-pylib-next command

* Let upgrade-pylib command to invetigate failing tests

* Add pre-commit review to invetigate-test-failure command

* Use deps command to get dependent tests in upgrade-pylib workflow

* Add f_trace_opcodes

Needed for bdb, and, by extension, pdb, to work.

Update `test__locale` from v3.14.2

* gc module internal structure and API

Add gc_state module with GcState, GcGeneration, GcDebugFlags, GcStats.
Replace gc module stubs with working API backed by gc_state.
Add gc_callbacks and gc_garbage to Context.
Add is_gc_tracked, gc_finalized, gc_get_referents to PyObject.
Collection is stubbed (returns 0) — actual algorithm to follow.

* fix dict/weakref/generators

* unmark test_asyncio

* apply review

descriptor.rs:
- Add __objclass__, __name__ (pymember) and __reduce__ (pymethod)
- Add type check (descr_check) in descr_get; simplify None branch
- Remove incorrect BASETYPE flag
- Add MemberKind::Object (_Py_T_OBJECT = 6)
- Prevent Bool slot deletion (TypeError)
- Raise AttributeError on ObjectEx deletion when already None

pyclass.rs (derive-impl):
- Remove duplicate MemberKind enum; use MemberKindStr (Option<String>)
- Simplify MemberNursery map key from (String, MemberKind) to String
- Support #[pymember(type="object")] for _Py_T_OBJECT semantics

test_inspect.py:
- Remove expectedFailure from test_getdoc (now passing)

Update `test_fork1` from v3.14.2

Add `source_path: PyMutex<&'static PyStrInterned>` field to
`PyCode` for interior mutability, replacing the UB-inducing
`#[allow(invalid_reference_casting)]` + `write_volatile` pattern
in `update_code_filenames`. Update all read sites across the
codebase to use the new `source_path()` accessor method.

… data (#7058)

* [update_lib] fix hard_dep not to unclude other tests

* [update_lib] commit test data

* `std` feature for common

- Gate OS-dependent modules behind `#[cfg(feature = "std")]`
- Replace `std::f64` with `core::f64` in float_ops
- Replace `std::process::abort` with panic in refcount
- Remove `thread_local` from levenshtein (stack buffer)
- Split static_cell into threading/non_threading/no_std

* `std` for codegen

* `no_std` for pylib

* temp regrtest save_env patch

* Refactor signal_handlers from Option to OnceCell

- Change `signal_handlers` type from `Option<Box<...>>` to
  `OnceCell<Box<...>>` so fork children can lazily initialize it
- Add `VirtualMachine::is_main_thread()` using runtime thread ID
  comparison instead of structural `signal_handlers.is_none()` check
- Initialize signal handlers in `py_os_after_fork_child()` via
  `get_or_init()` for workers that fork
- Use `get_or_init()` in `signal()` and `getsignal()` functions
- Remove `set_wakeup_fd(-1)` special-case workaround (d6d0303)
- Extract `signal::new_signal_handlers()` to deduplicate init expr
- Allow `getsignal()` from any thread (matches CPython behavior)
- Fix `set_wakeup_fd` error message to name the correct function

- Replace static_cell! cached builtins_iter/builtins_reversed with
  per-call vm.builtins.get_attr lookups to support runtime builtins
  mutation (CPython issue #101765)
- Refactor PositionIterInternal::reduce to take func, active, and
  empty callbacks; resolve builtins outside the lock to prevent
  deadlock from reentrant iterator access
- Add __reduce__ and fix reentrant next() in PyCallableIterator
- Remove expectedFailure from test_reverse_iterator_picking and
  test_reduce_mutating_builtins_iter

Update test_errno,test_iter from v3.14.3

Update `support.__init__.py` from 3.14.3

Update `test_array.py` from 3.14.3

For example in the following code:

    def foo(x: int, y: float):
        def bar(q: int):
            return q
        pass

Make sure that `foo` type annotations are correctly propogated to
it's `__annotate__` and `__annotations__` attributes.

With this chage, we'll get:

    >>>>> foo.__annotations__
    {'x': <class 'int'>, 'y': <class 'float'>}

Previously annotations where 'lost', and we would get:

    >>>>> foo.__annotations__
    {}

Update test_memoryview from v3.14.3 and impl count/index

Add `source_path: AtomicPtr<PyStrInterned>` field to `PyCode`
for interior mutability, replacing the UB-inducing
`#[allow(invalid_reference_casting)]` + `write_volatile` pattern
in `update_code_filenames`. Use atomic load/store instead of a
mutex since the operation is a simple pointer swap on a 'static
reference. Update all read sites to use `source_path()` accessor.

* Implement TypeAliasType, type annotations, and genericalias fixes

- TypeAliasType: lazy value evaluation via closures, __module__,
  __parameters__, __iter__, evaluate_value, check_type_params,
  IMMUTABLETYPE flag, Hashable/AsMapping/Iterable traits
- TypeAliasType constructor: positional-or-keyword arg validation,
  duplicate/unexpected kwarg rejection
- type.__annotations__ setter: distinguish None assignment from deletion
- Annotation scope: name as __annotate__, format as positional-only,
  __conditional_annotations__ uses Cell for both load and store
- Compiler: proper TypeParams/TypeAlias scope with closures,
  find_ann covers match/try-except handlers
- symboltable: deduplicate TypeAlias value scope code
- GenericAlias repr: handle list args, avoid deadlock in repr_arg
  by cloning items before calling repr
- AST types: remove IMMUTABLETYPE (heap types, mutable)
- pymodule macro: preserve existing __module__ getset descriptors

Wait for module initialization to complete when a module is
already in sys.modules but still being initialized by another
thread. Check __spec__._initializing and call
_lock_unlock_module to block until the import finishes.
