* Sync canonical Python 3.15 test maintenance
Apply update_lib cleanup and accounting, warning, and documentation updates while preserving stack-safety, Cargo path, and missing-native adaptations. Remove only unused helper and import remnants; do not add new tests or runtime claims.
Assisted-by: OpenAI Codex: model version unavailable
* Sync canonical SystemTap companion fixtures
Copy the existing expected trace and GC probe template through update_lib to match the already canonical consumer and Python input. Preserve the tracing capability gate; validate source consistency without invoking tracing tools or claiming provider support.

* Sync Python 3.15 core library tests and repr type errors
Synchronize ten selected library paths from CPython 3.15.0 at
d220409a13b77de7a6c30abe16ea90db01528edc using the canonical updater,
retaining existing RustPython adapters and failure markers.
Match generic __repr__ invalid-result errors to the qualified type-name
format required by the canonical ExceptionGroup regression, preserving
string results and exceptions raised by the implementation.
Implementation, source review, and validation were AI-assisted. The model
version identifier is unavailable; automated checks are not human
verification. Bounded validation covers 43 passes and one canonical skip,
not the full repository suites.

* Preserve original escape decoder consumed length after callbacks
Keep the original input length as consumed after successful unicode-escape
and raw-unicode-escape decoding, including error-handler input replacement.
Only report the current cursor when a non-final decode stops on incomplete
input, matching CPython's codec wrappers and incomplete exits.
Fix the canonical Unicode escape mutation regression that failed CI on
Linux, macOS and Windows. Preserve all Lib tests and existing assertions.
Bounded Linux validation: 55 passes and one canonical skip, CLI build and
strict common/VM Clippy passed. Full repository suites were not run.
Implementation, source review, and validation were AI-assisted. The model
version identifier is unavailable; automated checks are not human

* Take re pos/endpos as signed integers
Negative values clamp to 0, and values beyond Py_ssize_t raise
OverflowError.

* Port the remaining runtime fixes from #7993
- bytearray: keep the buffer exported while converting the needle of
find/count/index/rfind/rindex/__contains__/split/rsplit and the hex
separator, so resizing from there raises BufferError
- str(): report non-str encoding/errors as "str() argument 'X' must be
str, not T", and check argument counts and name/position duplicates
for keyword calls
- _json.scanstring: take end as a signed integer and raise ValueError
when it is out of bounds
- lzma: reject filter specs with keys the filter does not take
- mmap: raise ValueError when growing a shared anonymous mapping on
Linux/NetBSD
- _sqlite3: check that the backup progress argument is callable
- Remove the expectedFailure markers of the tests these fix

* Reject arguments given by name and position in FuncArgs::bind_for
bind_for reports a keyword that fills a parameter already given by
position before other binding errors, using the parameter list of the
FromArgs type. getargs shares the message, str() drops its own check,
and blake2b/blake2s name themselves in binding errors.
