* Align collections and testing libraries with Python 3.15
Refresh twelve production modules and canonical tests through scripts/update_lib at CPython d220409a13b77de7a6c30abe16ea90db01528edc. Preserve existing RustPython unittest helpers and test guards. Accept frozendict in native defaultdict and OrderedDict union slots, matching upstream PyAnyDict_Check without changing constructors, factories, or update order.
Validated as a local stack on the exact #9189 regex/dataclasses/typing prerequisite; this dependency avoids eager typing.ByteString deprecation during unittest warning tests.

* Synchronize regression runner with doctest subtest reporting
Refresh the canonical test_regrtest consumer and its direct runner/pythoninfo closure through scripts/update_lib at CPython d220409a13b77de7a6c30abe16ea90db01528edc. Preserve both existing expected-failure markers. This aligns the runner test with doctest reporting two failed examples and one skipped example.

* 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.

* Keep type dict keys and report current f_lasti
Snapshot the MRO during lookup so non-string keys can run __eq__,
skip subclass updates when set_bases is reentered, make module
__dict__ a readonly member, and forbid deleting exception __dict__.
f_lasti is the current opcode; line events skip NO_LOCATION units.

* Fire settrace call events from RESUME
PY_START/PY_RESUME become a 'call' event only at the first RESUME
of a frame activation, so lasti is the resume unit and f_trace_lines
is honored. Unskip passing TraceTestCase methods.
Assisted-by: Grok:grok-4.6
* Record what_event so f_lineno jumps match line traces
Store the current monitoring event while a trace callback
runs, reject jumps from call/return/exception, unwind tracer
errors in the traced frame, and fire call on PY_THROW.
Unskip JumpTestCase except the infinite-loop and five remaining xfails.
Assisted-by: Grok:grok-4.6
* Fire remaining settrace events from opcodes and jumps
Keep GET_ANEXT's iterator in mark_stacks, dispatch non-call
events through f_trace, fire PY_YIELD/PY_RETURN from the
opcodes, emit same-line LINE on backward jumps, and raise at
flattened call sites. Unskip the rest of test_sys_settrace.
Assisted-by: Grok:grok-4.6
* Fix trampoline raise panic and unxfail passing traces
Do not decode inline-cache units as opcodes when a flattened
call raises. Remove expectedFailure from test_trace and
test_regrtest coverage tests that now pass.
Assisted-by: Grok:grok-4.6
* Fire profile returns without a per-frame f_trace
setprofile must see PY_RETURN/PY_YIELD even when f_trace is unset.
Drop EXPECTED_FAILURE from the pdb doctest and unxfail
test_unfinished_generator.

When `ordered_attributes` is set, report attributes to the
StartElementHandler as a flat `[name, value, ...]` list matching
CPython's my_StartElementHandler, instead of always passing a dict.
`xml.etree.ElementTree` and `xml.dom.minidom` (via expatbuilder) both
enable this flag and rely on the flat-list contract, so parsing any
element with attributes previously failed: the dict made `_start` do
integer indexing, raising KeyError which was silently swallowed by the
handler invoker, leaving the tree empty ("missing toplevel element").
Reference (CPython 3.14):
https://github.com/python/cpython/blob/3.14/Modules/pyexpat.c#L439-L443
Remove `@unittest.expectedFailure` from tests that now pass
(23 in test_xml_etree, 15 in test_minidom, 1 in test_regrtest).
