* 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.

* Fix final script validation, exception cleanup and private cache contracts
Replay reviewed compiler CI repairs 2191a9d, 1f1fe04, a2dacaf on the frozen current prerequisite. Intermediate compile/diagnostic corrections are combined where they address the same failure.

* 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.

* Allow the c_long cast in _opcode.stack_effect
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
have no lock file, resolve it to 0.14.0 while the workspace pinned
0.13.0, and fail to build.
