Subject: [PATCH] Use typing.Self and drop the direct typing-extensions
 dependency

requires-python is >=3.14, so typing.Self (added in 3.11) is always
available. Importing Self from typing_extensions required a
# noqa: UP035 suppression of ruff's deprecated-import rule and made
typing-extensions a direct dependency for a single symbol.

- machine_learning/automatic_differentiation.py: import Self from typing
- pyproject.toml: remove typing-extensions from project dependencies
- uv.lock: drop the root direct edge (typing-extensions stays resolved
  transitively via beautifulsoup4/anyio, so the package set is unchanged)
