fix: resolve Windows 8.3 short paths in get_run_tmp_file and fix ruff lint errors

Add .resolve() to TemporaryDirectory path to expand Windows 8.3 short
paths (e.g. RUNNER~1) to canonical long form, fixing test_pickle_patcher
failures on Windows CI. Also add missing return type annotations and
noqa suppressions for benchmark test file.
