📝 Walkthrough

Walkthrough

This PR refactors scripts/fix_test.py to replace its line-based test modification system with a patch-based system using lib_updater. It introduces a --quick-import option for importing CPython test files, removes legacy AST-based functions, and updates test execution flags.

Changes

Cohort / File(s)	Summary
Patch-Based Test Modification System `scripts/fix_test.py`	Replaced AST-based test location and line-based modification logic with `lib_updater`-based patch system via new `build_patches` function; added `--quick-import` workflow to optionally copy CPython test files before patching; refactored argument parsing with mutual exclusive `--path`/`--quick-import` options; removed `find_test_lineno` and `apply_modifications` functions; updated test execution to include `-u all --slowest` flags; changed imports from `ast`, `itertools`, `platform` to `lib_updater` utilities.

The test-fixer script now takes its stand,
With quick-import swift and patches clean,
