* Update ten Python library modules to Python 3.15 final
Migrate dependency-ordered linecache, locale, _pydecimal, decimal, random, uuid, wave, _strptime, zipapp and poplib with their canonical tests and WAV fixtures using update_lib.

* Align dependent datetime and warning tests with Python 3.15 final
Generate complete dependent tests and pure datetime through update_lib from CPython d220409a13b77de7a6c30abe16ea90db01528edc. Preserve the existing tracemalloc expected failure. Pass warning module metadata to WarningMessage, use sys context after stack exhaustion, and identify invalid category classes with the existing qualified-name helper.

* Align compiler and VM with final CPython 3.15 bytecode
Reconstruct the compiler-only baseline from validated487ae47 on the current main and frozen mapping prerequisitec78d811. Preserve the full source delta while dropping obsolete prerequisite ancestry; detailed old-to-new provenance is retained in the recovery artifact.

* Align 3.15 code objects and codegen with CPython
- Store co_consts, co_names, co_localsplusnames, co_localspluskinds,
co_linetable, co_exceptiontable and co_name as objects on PyCode;
build co_code and the varnames/cellvars/freevars tuples lazily in
_co_cached, with co_code deoptimized through deopt_code.
- Move the compiler constant cache (_PyCode_ConstantKey,
const_cache_insert) to builtins/code/const_cache.rs.
- Write every code field with w_object in marshal and pass the read
field objects to MarshalBag::make_code through CodeFields.
- Emit RETURN_GENERATOR/POP_TOP in enter_scope and place SETUP_CLEANUP
after them; drop the generator part of insert_prefix_instructions.
- Add PyCode::first_traceable (_co_firsttraceable) for
_PyFrame_IsIncomplete and sys.monitoring.
- Follow the CPython DISABLE branches in sys.monitoring, the
check_matched signature in warnings, the 3.15 % format error
messages for str and bytes, code_returns_only_none, and the FOR_ITER
stack analysis.
- Compute IMPORT_NAME flags with in_exception_handler.
- Replace the linetable/exceptiontable byte tests in codegen with
dis(show_positions=True) insta snapshots in _opcode.
- Remove the opcode metadata verification tooling, byte-exact
scripts, private cache tests and redundant snippets.
- Restore test_code.py and test_monitoring.py to v3.15.0 plus
RUSTPYTHON markers.

* Remove generator snippet checks covered by Lib/test
Drop extra_tests/snippets/generator_iterator_prefix.py. Its loop,
delegation, async, f_back and never-awaited checks are covered by
test_generators, test_coroutines, test_asyncgen, test_yield_from and
test_monitoring. Move the remaining checks into existing files:
genexpr prefix tracing and monitoring into stdlib_sys.py, and the
caller frame seen from the eager iterator into stdlib_sys_getframe.py.

* Emit the generator prefix for top-level await modules
Module code compiled with PyCF_ALLOW_TOP_LEVEL_AWAIT and marked
ste_coroutine now starts with RETURN_GENERATOR; POP_TOP. The prefix and
RESUME emission move into emit_scope_prefix, shared by enter_scope and
the module entry points, as in codegen_enter_scope. Fixes
test_builtin.test_compile_top_level_await.

c_long is i32 on Windows, where clippy reports the cast to i32 as
unnecessary.

* Update malachite crates to 0.14.0
pymath requires malachite-bigint ^0, so the example projects, which

0.13.0, and fail to build.

* Implement _collections.OrderedDict
Extracted from #6799: native OrderedDict as a dict subclass,
iterator mutation tracking, and mapping-view set operations.
* Add OrderedDict, warnings source lines, and socket sendmsg
Implement _collections.OrderedDict as a dict subclass with a
linked list of insertion-order nodes.
Pack struct F/D as native float/double complex pairs, and report
unexpected __replace__ field names as a list repr.
Register encodings.latin_1 at startup. Reject NUL in input()
prompts. Copy non-exact type dicts in mapping order.
Fetch warning source lines through _bless_my_loader and unicode
splitlines. Keep the last warnings.filters list after deletion.
Snapshot sendmsg sequences before converting buffers, parse
ancillary ints with __index__, and dispatch AF_CAN by protocol.
Store sys.trace and sys.profile on each ThreadSlot so
_settraceallthreads/_setprofileallthreads are visible to
sys.gettrace/getprofile on other threads.
Use <frozen importlib._bootstrap> as frozen importlib
co_filename. Keep HEAPTYPE socket objects GC-tracked.

* Load marshal via readinto and dump sets in dumps order
marshal.load fills a scratch buffer with readinto on a
contiguous writable memoryview, and rejects a returned length
other than the requested size.
set and frozenset dumps write elements in sorted(v,
key=marshal.dumps) order.
Assisted-by: Grok:grok-4.6
* Add classmethod_descriptor and ABC IS_ABSTRACT flags
Give METH_CLASS methods a distinct classmethod_descriptor type.
Store Py_TPFLAGS_IS_ABSTRACT from __abstractmethods__ and look
up that attribute only in the type's own dict.
Expose defaultdict.default_factory as a member descriptor.
Inherit bool's unused number slots from int. Mark set and
frozenset __contains__ as METH_COEXIST.
Parse classmethod, staticmethod, object.__new__, and heap type
text signatures. Register interactive source in linecache.
Assisted-by: Grok:grok-4.6
* address review: odict reuse, descr call, new wrapper
Reuse odict node slots and walk the live list in next_after.
Require both | operands to be dicts. Drop the odict iterator
on GC clear. Bind classmethod descriptors through descr_get
and update IS_ABSTRACT under the type lock. Give odict keys
and items sq_contains. Walk tp_new_wrapper past new_wrapper
so HEAPTYPE socket subclasses can call socket.__new__.
Split FreeBSD Bluetooth protocol constants from Linux values.

Give _pickle.Pickler the clinic constructor text signature and
accept fix_imports and buffer_callback as positional-or-keyword.
Allow #[pyfunction(text_signature)] and use it so os.stat reports

pass.
