gh-143650: Fix importlib race condition on import failure (GH-143651)
Fix a race condition where a thread could receive a partially-initialized
module when another thread's import fails. The race occurs when:
1. Thread 1 starts importing, adds module to sys.modules
2. Thread 2 sees the module in sys.modules via the fast path
3. Thread 1's import fails, removes module from sys.modules
4. Thread 2 returns a stale module reference not in sys.modules
The fix adds verification after the "skip lock" optimization in both Python
and C code paths to check if the module is still in sys.modules. If the
module was removed (due to import failure), we retry the import so the
caller receives the actual exception from the import failure rather than
a stale module reference.

Modifies handling of `.gz` files in Android app payloads, and ensures that

gh-126014: test_makefile_test_folders: Ignore basically-empty directories (GH-140466)
The code in test_makefile was attempting to ignore any
non-interesting files, but missed some corners:
1. There is never a *file* called `__pycache__`.
2. A directory containing only a `__pycache__` subdirectory should be
ignored.
3. A directory containing only hidden files should be ignored.
Simplify this all into a couple of filters that let us check for empty
lists.

gh-143935: Email preserve parens when folding comments (GH-143936)
Fix a bug in the folding of comments when flattening an email message
using a modern email policy. Comments consisting of a very long sequence of
non-foldable characters could trigger a forced line wrap that omitted the
required leading space on the continuation line, causing the remainder of
the comment to be interpreted as a new header field. This enabled header
injection with carefully crafted inputs.

gh-143774 - Improve IDLE Format Paragraph doc (GH-143775)
Add a reminder to not rewrap code line to the Menu => Format => Reformat Paragraph entry.
In Editing and Nagivagion, add a new 'Format block' subsection that defines 'paragraph'
to better match what is dependably handled as more or less expected.
In particular, specify equal indents and that the resulting indent equals original indent.
Also mention that selections are expanded to complete lines and how to modify max length.
(Also fix a couple case errors in cross references.)

Copy net new text in idle.rst from main to 3.13.
Make 3.13 docs and copy-strip idle.html to idlelib/help.html.
See https://github.com/python/cpython/issues/139707#issuecomment-3737374788
and PR #143718 message for more.
* Revert url to 'main' from '3.13'
The branch in the source links in the revised help.html
become '3.13' instead of 'main' because the html
was generated from an edited 3.13 version of idle.rst
instead being backported from main. This reversion
avoids the possibility of future backport merge conflicts.
The version makes no difference to the Help/IDLE doc display as
the url is currently neither displayed nor linked to the link title
-- 'Lib/idlelib'. If we do make the links live, we can use
sys.version_info to replace 'main' when main is no longer the source branch.
