build(deps): Upgrade pytest to v9 and refine configuration

Upgrade the `pytest` dependency from version 8 to version 9. This change also includes migrating the `pytest` configuration in `pyproject.toml` from the legacy `[tool.pytest.ini_options]` section to the modern `[tool.pytest]` section.

Further refine the `pytest` configuration by:
- Adding `strict = true` to enforce stricter test collection and execution.
- Explicitly defining `testpaths` to include `benches`, `src`, and `tests`.
- Reordering the `[dependency-groups]` for improved readability and consistency.
- Correcting a trailing comma in the `Typing :: Typed` classifier for better formatting.
