Fix the missing field in the new into_base initializer without changing its pointer or ownership transfer.
Assisted-by: OpenAI Codex: model identifier unavailable
Co-authored-by: dot <dot@youknowone.org>
PyRef::into_base and Py::to_base cast the pointer directly instead of
going through a class-based downcast. into_base no longer reaches
unreachable_unchecked when the object's MRO omits the native base, and
to_base drops the equivalent debug assertion.

- Problem: WASM_WASI_SNIPPETS only declared 2 of 244 extra_tests/snippets
files, so every newly-fixed snippet needed a manual ci.yaml edit to gain
wasm-wasi coverage
- Fix: loop over extra_tests/snippets/*.py directly and skip only the 57
files that still fail, hang, or are intentionally-failing
(WASM_WASI_SNIPPET_EXCLUDE), so fixed and future snippets run automatically
- Verified: built wasm32-wasip1 from current upstream/main, ran all 244
snippets; the 187 non-excluded files pass 3x repeated runs with no
flakiness (~48s total, well under the 30-minute job budget); the 57
excluded files were categorized (missing modules, threading disabled in
this build, 32-bit overflow, no process support on WASI, wasm call-stack
limits, socket stub, sandbox path issues, and a couple of individual bugs)

* 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

the patch and regression snippet, and ran the reported validation. The
