Updates the warnings module to CPython 3.14.1 as part of the Python 3.14 library upgrade effort.

Changes

  • Library files: warnings.py and _py_warnings.py already matched CPython 3.14.1 (no changes)
  • Test files: Applied CPython 3.14.1 test updates with formatting normalization (spacing after TODO markers)
  • Build config: Added cpython/ to .gitignore

Test Status

183 tests pass (46 expected failures, 10 skipped for CPython implementation details)

@copilot Run: python scripts/update_lib quick warnings . Didn't warnings.py changed?

Ran python scripts/update_lib quick cpython/Lib/warnings.py as requested. The files warnings.py and _py_warnings.py are already identical to CPython 3.14.1, so no changes were needed. The update tool confirmed this by showing "nothing to commit, working tree clean" after processing.
