gh-130959: Reject whitespace in fractions, in pure Python `fromisoformat()` (#130962)
Fix the pure Python implementation of `fromisoformat()` to reject any
non-digit characters, including whitespace, in the fractional part
of time specification. This makes the behavior consistent with the C
implementation, and prevents incorrect parsing of these fractions
(e.g. `.400 ` would be misinterpreted as `.04`).

gh-123726: Document caveats of zipfile.Path around name sanitization (GH-130537)
Add a note to the `zipfile.Path` class documentation clarifying that it does not sanitize filenames. This emphasizes the caller's responsibility to validate or sanitize inputs, especially when handling untrusted ZIP archives, to prevent path traversal vulnerabilities. The note also references the `extract` and `extractall` methods for comparison and suggests using `os.path.abspath` and `os.path.commonpath` for safe filename resolution.

The test could deadlock trying join on the worker processes.
Apply the same technique as gh-130933.
Join the process before the test ends in `test_notify` as well.
(cherry picked from commit edd1eca336)
Co-authored-by: Sam Gross <colesbury@gmail.com>
The free-threading build interns and immortalizes most constants
generated by the bytecode compiler. However, users can construct their
own code objects with arbitrary constants. We should not intern or
immortalize these objects if they are not of a type that we know how to
handle.
This change fixes a reference leak failure in the recently added
`test_code.test_unusual_constants` test. It also addresses a potential
crash that could occur when attempting to destroy an immortalized
object during interpreter shutdown.
(cherry picked from commit 12db45211d)
The workload to advance the virtual timeout is too lightweight for some
platforms. As result the test goes in timeout as it never reaches the
end of the timer. By having a heavier workload, the virtual timer
advances rapidly and the SIGVTALRM is sent before the timeout.

The test could deadlock trying join on the worker processes due to a
combination of behaviors:
* The use of `assertReachesEventually` did not ensure that workers
actually woken.release() because the SyncManager's Semaphore does not
implement get_value.
* This mean that the test could finish and the variable "sleeping" would
got out of scope and be collected. This unregisters the proxy leading
to failures in the worker or possibly the manager.
* The subsequent call to `p.join()` during cleanUp therefore never
finished.
This takes two approaches to fix this:
1) Use woken.acquire() to ensure that the workers actually finish
calling woken.release()
2) At the end of the test, wait until the workers are finished, while `cond`,
`sleeping`, and `woken` are still valid.

The bytecode compiler only generates a few different types of constants,
like str, int, tuple, slices, etc. Users can construct code objects with
various unusual constants, including ones that are not hashable or not
even constant.
The free threaded build previously crashed with a fatal error when
confronted with these constants. Instead, treat distinct objects of
otherwise unhandled types as not equal for the purposes of deduplication.

gh-128388: pyrepl on Windows: add meta and ctrl+arrow keybindings (GH-128389)
Fix `Lib/_pyrepl/windows_console.py` to support more keybindings, like the
`Ctrl`+`←` and `Ctrl`+`→` word-skipping keybindings and those with meta (i.e. Alt),
e.g. to `kill-word` or `backward-kill-word`.
Specifics: if Ctrl is pressed, emit "ctrl left" and "ctrl right" instead of just "left" or
"right," and if Meta/Alt is pressed, emit the special key code for meta before
emitting the other key that was pressed.

gh-130740: Move some `stdbool.h` includes after `Python.h` (#130738)
Move some `#include <stdbool.h>` after `#include "Python.h"` when `pyconfig.h` is not
included first and when we are in a platform-agnostic context. This is to avoid having
features defined by `stdbool.h` before those decided by `Python.h` (this caused some
build failures when compiling CPython with `zig cc`).

gh-128481: indicate that the default value for `FrameSummary.end_lineno` changed in 3.13 (GH-130755)
The value taken by `FrameSummary.end_lineno` when passing `end_lineno=None` changed in gh-112097.
Previously, a `end_lineno` could be specified to be `None` directly but since 939fc6d, passing None makes
the constructor use the value of `lineno` instead.
