* Refresh Python 3.15 HTTP, URL and documentation libraries
Import the connected documentation and HTTP/URL library closure from CPython d220409a13b77de7a6c30abe16ea90db01528edc using scripts/update_lib. Preserve surviving RustPython test guards; the upstream-removed CGI test class has no remaining marker target.

* Retire obsolete wsgiref file-wrapper test forwarder
Canonical Python 3.15 removed the target method; migrate with an empty marker override rather than retain an expected-failure call to a nonexistent super method.

* Adapt pydoc classification to the Cargo source layout
Expose the existing source-directory predicate as sys._is_python_build and regenerate pinned pydoc with the explicit updater transform shared with the mega repair. Installed layouts and explicit basedir arguments retain upstream behavior.

* Expose source-directory classification on every platform
The existing platform-neutral Lib and Cargo.toml predicate is needed by sys._is_python_build on all platforms; preserve its algorithm unchanged.

* Unskip passing flaky CPython tests
Remove RUSTPYTHON skip overlays after Linux release repeats passed
for enum, threading, logging, subprocess, socket, int, re, strtod,
and regrtest cases.

* Fix fork-child SIGSEGV and yield-from throw args
Forget JoinHandle of threads that did not survive fork instead
of dropping them. Zero-reinit the import lock and condvars in
the child rather than unlock/notify. Resume the world if
os.fork() fails.
Call a yield-from subiterator throw() without None fillers so
a 1-arg throw stays 1-arg.
Drop the stale Windows expectedFailure on logging queue config
and unskip test_reinit_tls_after_fork plus the asyncio
local_addr family test.

* Restore import lock depth after fork; add WASI clock info
Zeroing IMP_LOCK in the child discarded its recursion count, so
imp.release_lock() raised and test_fork1 exited 1. Re-acquire the
saved depth, then drop the extra pre-fork hold.
Expose time.get_clock_info on WASI via clock_getres so test_int
Stopwatch can run.
Unskip lock_tests test_acquire_contended and test_thread_leak.

* Honor chmod follow_symlinks=False via fchmodat
Linux chmod followed the symlink, so dangling links raised
FileNotFoundError instead of NotImplementedError. Use fchmodat
with AT_SYMLINK_NOFOLLOW and map ENOTSUP to NotImplementedError.
Unskip httpservers truncated Content-Length (CPython already
skips as root) and tempfile symlink-mode cleanup on Linux.

* Unskip httplib local bad-hostname HTTPS test
The skip was leftover. With default ssl-rustls the test passes
under -W error on Linux.

* Fix list cmp deadlock, wasm digit overflow, REPL prompt
Do not hold list/deque locks across item comparison callbacks.
Compute int-to-str digit bounds in u64 so the check cannot wrap
on wasm32. Snapshot set contents when list.extend copies a set.
For a non-TTY stdin, write the REPL prompt to stderr and read
lines from stdin. Flush stdout/stderr after each interactive
command. Set sys.ps1/ps2 to ">>> " and "... ".
Unskip list mutation compares, asyncio all_tasks race, importlib
deadlock/parallel/circular-import tests, and REPL stdout flush.

* Avoid unnecessary u64 cast in int-to-str digit check
bits() is already u64, so `bits as u64` fails clippy
unnecessary_cast under -Dwarnings.
Assisted-by: Grok:4.6
* Updated urllib + urllib tests
* Updated http + test
* Annotated failing tests
* Fixed issues in httpservers, robotparser and urllib2net
* Fixed windows only success
* Annotated flaky test in test_logging
Initially this is only meant to be a small update for `test_io.py`.
But it turns out that `test.support` need a lot of cleanup especially
for `test.support.warnings_helper`.
