Fix upstream ci-lint failures on this branch

- autosave.py: black formatting (blank line) and ruff's
  collections.abc.Callable import fix.
- project/__init__.py, tool/__init__.py: ruff import-sort fixes. The
  autosave import in tool/__init__.py is deliberately kept last (must
  come after tool.drawing, per its existing comment) via `# isort: skip`
  rather than letting ruff move it, which would reintroduce that bug.

Generated with the assistance of an AI coding tool.
