gh-134411: assert `PyLong_FromLong(x) != NULL` when `x` is known to be small (GH-134415)

Since `PyLong_From Long(PY_MONITORING_DEBUGGER_ID)` falls to `small_int` case and can't return `NULL`. Added `assert`s for extra confidence.

gh-136428: amend UUIDv8 performance improvements (GH-136903)

UUIDv8 has been added in Python 3.14.0a2 and its construction time
has been improved in Python 3.14.0a4, but since those changes will
not be visible when comparing the latest Python 3.13 and 3.14 together,
we do not document them on the What's New page to avoid confusion.

Extend the documentation for disabling pymalloc with the `--without-pymalloc` flag regarding why it is worth to use it when enabling AddressSanitizer for Python build (which is done, e.g., in CPython's CI builds).

I have tested the CPython latest main build with both ASan and pymalloc enabled and it seems to work just fine. I did run the `python -m test` suite which didn't uncover any ASan crashes (though, it detected some memory leaks, which I believe are irrelevant here).

I have discussed ASan and this flag with @encukou on the CPython Core sprint on EuroPython 2025. We initially thought that the `--without-pymalloc` flag is needed for ASan builds due to the fact pymalloc must hit the begining of page when determining if the memory to be freed comes from pymalloc or was allocated by the system malloc. In other words, we thought, that ASan would crash CPython during free of big objects (allocated by system malloc). It may be that this was the case in the past, but it is not the case anymore as the `address_in_range` function used by pymalloc is annotated to be skipped from the ASan instrumentation.

gh-136839: Refactor simple dict.update calls (GH-136811)

Refactor simple dict.update calls

This commit refactors simple `dict.update({key: value})` calls which can
be done via `dict[key] = value` instead.

I found those cases with the [semgrep](https://semgrep.dev/) tool:

```
$ semgrep --lang python --pattern '$DICT.update({$A: ...})'

[3.14] Docs: Improve example for `itertools.batched()` (GH-136775) (#136778)
Docs: Improve example for ``itertools.batched()`` (GH-136775)

The current example `batched('ABCDEFG', n=3) → ABC DEF G` can confuse readers because both, the size of the tuples and the number of tuples are 3.
By using a batch size of n=2, it is clearer that the `n` argument refers to the size of the resulting tuples.
I.e. the new example is: `batched('ABCDEFG', n=2) → AB CD EF G`

Clears the umask used during a test of pydoc.apropos when testing on
Emscripten. This is to work around a known issue in Emscripten; but it's not
clear if the chmod call that is causing the problem is actually testing
anything of significance.

This might have been fixed by gh-136624, or by some Emscripten change.
In any case, it no longer seems to be needed.

Previously, we assumed that instrumentation would happen for all copies of
the bytecode if the instrumentation version on the code object didn't match
the per-interpreter instrumentation version. That assumption was incorrect:
instrumentation will exit early if there are no new "events," even if there
is an instrumentation version mismatch.

To fix this, include the instrumented opcodes when creating new copies of
the bytecode, rather than replacing them with their uninstrumented variants.
I don't think we have to worry about races between instrumentation and creating
new copies of the bytecode: instrumentation and new bytecode creation cannot happen
concurrently. Instrumentation requires that either the world is stopped or the
code object's per-object lock is held and new bytecode creation requires holding
the code object's per-object lock.
