fix: Address runtime errors and improve configuration

Browse Source 
This commit addresses several runtime errors encountered during the execution of the `speedrun.sh` script and improves the overall configuration of the project.

The key changes are:
- Patched `nanochat/configurator.py` to be more robust by handling flag-like arguments and ignoring unknown arguments. This resolves the `AssertionError`.
- Fixed the argument handling for `chat_eval.py` in `speedrun.sh` to prevent argument parsing errors.
- Updated `pyproject.toml` to correctly define optional dependencies for development.
