* Align duplicate-parameter diagnostics with Python 3.15
Preserve source names and locations in both symbol-table paths, and migrate
the existing canonical codeop expectation through update_lib.

* Sync positional-only duplicate-parameter expectations
Migrate the full pinned CPython 3.15.0 test file through update_lib. Its only delta is six existing expected messages, completing the dependent canonical wording coverage.

* Mark wrapper descriptors as method descriptors
Match CPython 3.15 wrapper_descriptor flags so existing method lookup
can use the descriptor's direct receiver-prepending dispatch path.

* Retire fixed wrapper monitoring expected failure
Regenerate test_monitoring from pinned CPython 3.15.0 with the updater, preserving every other adaptation. The METHOD_DESCRIPTOR flag now supplies the canonical receiver in int.__repr__ CALL/C_RETURN events.

Accept the module keyword when building symbol tables and emit only parser
warnings through the existing bounded warning path. Preserve source filenames

Collect representable constants before replacing append-sequence instructions
with NOPs. A valid LOAD_COMMON_CONSTANT may not have a ConstantData value, so
returning false must leave the helper's instruction sequence unchanged.
Cover list, set and ListToTuple tails with a direct native IR invariant.
No change to normal constant-folding behavior or canonical Lib tests.

* Factor shared interpreter stop-the-world guard
Move the existing collector barrier into the VM without changing its stop, restart or ownership behavior, preparing reuse by fork.
Assisted-by: dot:GPT-6.1
* Add interpreter-bound operation section primitive
Prepare attached-only ownership acquisition and detached observer parking with private per-interpreter scope stacks. Lifecycle wiring follows separately; no profiler consumer is enabled by this commit.
Assisted-by: dot:GPT-6.1
* Suspend operation sections at VM lifecycle boundaries
Integrate detach, stop-the-world, shutdown and interpreter-switch boundaries. Reuse the all-interpreter barrier for fork repair and add focused native ownership invariants.
Assisted-by: dot:GPT-6.1
* Replace operation sections with PyMutex critical sections
Add PyMutex with the lock.c protocol: LOCKED/HAS_PARKED bits, a bounded
spin, direct handoff to waiters parked longer than 1 ms, and detaching
while parked.
Rebuild critical sections on PyMutex with the stack kept as a tagged
pointer in ThreadSlot: single and two-mutex sections, recursive
top-most skipping, locking skipped while the world is stopped,
SuspendAll on detach/suspend/shutdown and Resume of the top-most
section on attach. Fork carries the stacks into the replacement slots.
Assisted-by: Claude Code:claude-opus-5-5
* Check attachment around critical-section suspension
Assert that a thread entering a critical section is attached, and
suspend sections in do_suspend only while the slot is still ATTACHED.

* Use the RustPython Ruff fork 0.17.1 from git and place EOF errors by kind
- The ruff crates come from the RustPython/ruff `rustpython-0.17.1`
branch at 93967836c8 instead of the 0.16.10 crates.io release.
- `EofToken.known_location` is replaced by `EofErrorLocation`
(Tokenizer, Token, StartingFromToken), chosen from the parse error kind.
The keyword scan in `clause_keyword` is removed, since the parser now
reports a forced `:` as `ExpectedForcedToken`.
- An empty import at EOF ends at the end of the line read, and an empty
import before a newline is an empty range at the newline.

* Report the obsolete `<>` from the parser outside Barry mode
- Bump the RustPython/ruff fork to 9290a88495, where the parser reports an
adjacent `<` and `>` in a comparison as "invalid syntax. Maybe you meant
'!=' instead of '<>'?" over both tokens.
- Outside Barry mode, `BarrySource` no longer searches the source text for
`<>`, so the parser's error is reported unchanged. A `<>` that starts a
statement is reported at the `<` only, and `<<>` at the `>`.

* Rework signal wakeup error delivery to follow signalmodule.c
- Report pending wakeup write/send errors after Python signal handlers
and VM pending calls, and re-arm the eval breaker when a handler or
pending call raises.
- Save and restore errno once in run_signal around trip_signal instead
of inside each write path; stop preserving _doserrno.
- Add crt_fd::write_noraise and use it for the Unix and Windows wakeup
writes, sharing the single-write helper with _write.
- Keep pending wakeup errors across fork.
- Revert the suppress_iph handler type change and the unrelated quote
change in test_signal.

* Represent nullable Windows CRT parameter handlers as Option
_set_thread_local_invalid_parameter_handler takes and returns a nullable

EnumerateArgs bound the iterable as PyIter, so argument binding called
__iter__ before start was converted and before surplus positional
arguments were rejected. An exception from __iter__ then replaced the
TypeError CPython raises for a bad start or a third argument.
Bind the iterable as an object and call get_iter() in py_new, after
start is converted, which is the order of CPython's enum_new_impl.

CPython keeps a Neumaier compensation term while sum() accumulates an
exact float or complex, and reaches that path from an exact int start
too. RustPython added items one by one, so sum([0.1] * 10) returned
0.9999999999999999 instead of 1.0.
Port the int, float and complex fast paths of builtin_sum_impl, each
falling back to plain addition at the first item it does not handle.
