youknowdot e09846b4eb Fix bytearray membership racing with resizing (#9091 )

* Fix bytearray membership racing with resizing

Search exact bytes and int needles under the data read lock instead of
taking a temporary export. This prevents a concurrent slice replacement
from receiving BufferError for a callback-free membership operation.

Preserve export protection for generic index/buffer callbacks and actual
memoryviews. Add Python coverage for these contracts.

AI assistance: Codex/OpenAI diagnosed the race, implemented and reviewed
the patch and regression snippet, and ran the reported validation. The
runtime did not expose an exact model version.

* Handle bool needles and consolidate bytearray regression coverage

Include exact builtin bool in the callback-free integer membership path.
Keep int subclasses and generic conversion paths under export protection.
Move this PR's regression coverage into the existing bytearray snippet
and cover True/False membership as requested in review.

AI assistance: Codex/OpenAI implemented and independently reviewed the
review follow-up and ran the reported validation. The runtime did not
expose an exact model version.

Test snippets

This directory contains two sets of test snippets which can be run in Python. The snippets/ directory contains functional tests, and the benchmarks/ directory contains snippets for use in benchmarking RustPython's performance.

Setup

Our testing depends on pytest, which you can install using pip.

Running

Simply run pytest -v in this directory, and the tests should run (and hopefully pass). If it hangs for a long time, that's because it's building RustPython in release mode, which should take less time than it would to run every test snippet with RustPython compiled in debug mode.
