* Borrow tp_descr_get/tp_init arguments and by-value public helpers
- DescrGetFunc and GetDescriptor::descr_get take
(&PyObject, Option<&PyObject>, Option<&PyObject>); impls call
.to_owned() where they store or return an argument.
- InitFunc takes &PyObject and Initializer::init takes &Py<Self>.
- VirtualMachine::get_attribute_opt, print_exception,
call_get_descriptor(_specific) and other helpers flagged by
clippy::needless_pass_by_value take &PyObject / &Py<T>; callers in
crates/, examples/ and tests/ drop the clones made for the call.

* Pass the borrowed zelf to internal_close in WindowsConsoleIO init
Assisted-by: Claude Code:claude-opus-5-5
* Fix borrowed signatures missed by the rebase
OrderedDict.init, classmethod_descriptor.descr_get, and the warnings
get_attribute_opt callers still used owned handles.

* Unskip multiprocessing RLock repr test

* Drop stable modules from the flaky MP CI list

* Keep only multiprocessing fork on the flaky MP list

* Drop gc_collect bench and unbreak two CI jobs
Remove benches/benchmarks/gc_collect.py so CodSpeed no longer
includes that execution benchmark.
On Windows, run test_multiprocessing_spawn serially; the
parallel snippets job hit a regrtest worker temp-dir error
while that suite was still running.
Install cargo-shear from a pinned prebuilt binary so the job
does not fall back to compiling 1.13.4 from source.

* Unskip hang tests that now pass under -m test
Drop the RustPython hang skips on interpreter shutdown,
submit-after-shutdown, and connection pickling after they
passed with rustpython -m test.
Remove the unused expectedFailureIf around killpg on the
resource tracker deadlock test; os.killpg is present.
Pass matrix flaky-MP extras through the job environment
instead of interpolating them into the run script.

* Restore hang skips and isolate spawn on CI
Put test_multiprocessing_spawn and
test_multiprocessing_forkserver back on the serial flaky MP
list. Ubuntu timed out in spawn test_notify_all under -j, and
forkserver.test_processes needed a rerun.
Restore the hang skips on interpreter shutdown, submit-after
shutdown, and connection pickling.

Add dependency-free CPU-bound workloads adapted from pyperformance 1.14.0 to cover interpreter, standard-library serialization, regex, numeric, and garbage-collection paths under the existing Criterion and CodSpeed harnesses. Keep inputs deterministic and scale expensive cases for simulation while checking that benchmark execution does not leak interpreter state.
