Bump beartype to 0.23.0rc0

[adamtheturtle]

Tests the beartype 0.23.0rc0 release candidate against this repository's test suite.

Pins beartype to the release candidate in pyproject.toml and updates uv.lock to match.

Not intended to merge as-is — the pin should be relaxed once the release candidate has been evaluated.

Note

Medium Risk
Beartype decorates most public API entry points, so an RC pin could change runtime type-check behavior; import-only edits are low risk but touch many modules.

Overview
Pins beartype to 0.23.0rc0 in pyproject.toml (from >=0.22.9) so CI can exercise the release candidate against the full test suite; the lockfile is updated to match.

Across src/vws and tests, type-only imports that used # noqa: TC003 are moved behind if TYPE_CHECKING: blocks (e.g. Response, Transport, VuMarkAccept, io, Generator). Runtime import graphs stay lean for @beartype while annotations remain unchanged.

Closing: this was a test balloon for the beartype 0.23.0rc0 release candidate, not a change to merge. CI was green on the version bump.
