fix: regenerate poetry.lock to match pyproject.toml (#140)

poetry.lock had drifted from pyproject.toml ('pyproject.toml changed
significantly since poetry.lock was last generated'), which made CI emit
'poetry.lock is not consistent with pyproject.toml. You may be getting
improper dependencies.' on every build. Re-locked with Poetry 2.3.2; the
only changes are the content-hash, generator version, and a normalized
version constraint — no dependency versions change.
