fix: add missing packaging dependency (#54)

* fix: add missing packaging dependency

The replicate.lib._schema module imports the packaging library
but it wasn't listed as a dependency in pyproject.toml, causing
ModuleNotFoundError when the module is imported.

Fixes import error: "ModuleNotFoundError: No module named 'packaging'"

* Update uv.lock

by running `uv sync`
