* Align weak-reference collection with Python 3.15 finalization
Trace and retain owned callback edges independently of weak referent links.
Clear callback-bearing weakrefs before finalizers, suppress callbacks from
unreachable weakrefs, and close remaining weakref ingress after resurrection
checks while the world is stopped. Publish and unlink intrusive nodes safely.
Refresh weakref and canonical weakref/GC/finalization tests through update_lib
from pinned CPython 3.15.0. Retire four obsolete guards only after fresh body
passes, retaining applicable RustPython limitations.

* Refresh canonical IO tests for weakref finalization
Migrate the complete CPython 3.15.0 test_io package at d220409 with the
fail-closed legacy-map updater, preserving all ten existing guards. Retire
the seven consolidated standalone suites and update io/file dependency
paths with mapping regression tests.
The canonical GC tests ignore ResourceWarning without retaining its
source, so callback-free weakrefs correctly reflect surviving owners.
This closes the stale test dependency exposed by the lifecycle change.

* Protect weakref callbacks with the original referent stripe
Follow CPython's free-threading weakref locking model instead of keeping
an independent callback RwLock. Retain the original referent stripe key
so callback access stays synchronized after GC clears the referent.
Unlink and steal callbacks under that stripe, then release ownership
outside the lock. Preserve synchronization for running-world GC paths
and gc.get_referents while keeping ordinary weakref upgrades unchanged.

* Defer weakref GC tracking until referent publication
Keep freshly allocated weakrefs out of GC's object lists until they are
linked and their referent is published. Release the referent stripe before
tracking, since tracking can collect and invoke finalizers. Generic reuse
losers remain untracked.
Exercise the allocator boundary directly for reference, proxy, callable
proxy and subclass payloads, and ensure completed constructors track their
objects. This prevents observers from retaining a half-built dead weakref
that later becomes live.

* Retain the original weakref stripe lock like CPython
Store a safe handle to the selected static weakref stripe instead of
retaining and rehashing the referent address. Keep the same lock after
referent clearing, matching CPython free-threaded weakrefs_lock. The
nonthreaded handle is zero-sized and introduces no locking.
Preserve lock selection, acquire/release ordering, fork reset, deferred
GC publication, and callback-owner release outside the stripe. No new
locks or unsafe code are needed.

* Add Python 3.15 math APIs using pymath
Pin pymath to merged dd1e9a4cf26d68caf3b549c09476f52e356e16a3
and expose isnormal, issubnormal, signbit, fmax and fmin through thin
wrappers. Share the existing integer functions through math.integer
and _math_integer, matching CPython module identity and metadata.
Migrate test_math.py and test_math_integer.py via scripts/update_lib
from CPython d220409a13b77de7a6c30abe16ea90db01528edc, preserving the
existing Windows remainder marker. Add bounded Python snippet coverage.

* Make auto-mark output deterministic and fix blank line leak
Sort set iteration in build_patches and dict iteration in
_iter_patch_lines Phase 2 so expectedFailure markers are
always added in alphabetical order.
Include preceding blank line in _method_removal_range so
removing a super-call override doesn't leave behind the
blank line that was added with the method.
