fix(deps): Pin pydantic below 2.12.0 for compatibility (sooperset#732)

The latest pydantic version (2.12.0) is not compatible with the project's current usage.
Updates dependency specification in `pyproject.toml` to "pydantic>=2.10.0,<2.12.0" to prevent runtime errors when using with uvx.

Related to sooperset#721.
