Use pytest-beartype-tests plugin

[adamtheturtle]

This PR adds the pytest-beartype-tests dev dependency and removes redundant pytest_collection_modifyitems / @beartype wiring from conftest where it duplicated the plugin.

The plugin registers via pytest11 and applies @beartype to collected test functions, matching the previous local hook behavior (see the upstream README).

Note

Low Risk
Low risk: this only changes test-time type checking wiring by delegating @beartype application to an external pytest plugin, so impact is limited to how tests are collected/executed.

Overview
Moves beartype enforcement for tests from a custom pytest_collection_modifyitems hook in tests/conftest.py to the pytest-beartype-tests plugin.

Adds pytest-beartype-tests as a dev dependency (with a uv git source pin) and removes the now-redundant local beartype import/hook, plus drops the related Vulture ignore entry.

Unpinned non-PyPI dependency breaks pip-based dev install

Medium Severity

pytest-beartype-tests is added to optional-dependencies.dev without a version pin and does not appear to be published on PyPI — it's only resolvable via the uv-specific [tool.uv] git source. Every other dev dependency has an explicit version pin. The project's contributing docs (docs/source/contributing.rst) instruct contributors to run pip install --editable '.[dev]', which will now fail because pip doesn't read [tool.uv.sources] and can't find the package on PyPI.
