* migrate to pyright * Refactor type checking to use Pyright, update dependencies, and clean up code. - Replaced MyPy with Pyright in configuration files and CI workflows. - Updated `pyproject.toml` and `uv.lock` to reflect new dependencies and versions. - Adjusted type hints and fixed minor code issues across various modules for better compatibility with Pyright. - Added new packages `backoff` and `posthog` to the project dependencies. * Update CI workflows to install all extra dependencies for type checking and unit tests * Update dependencies in uv.lock to replace MyPy with Pyright and add nodeenv package. Adjust type hinting in config.py for compatibility with Pyright.
