Code Review

This pull request adapts the project for pyrefly, a static analysis tool, by adding its configuration and removing the ty dependency. The changes are mostly configuration-related. I've found a few areas for improvement, mainly regarding a missing import for a new type hint and some redundancies in the new pyrefly.toml configuration file that could be cleaned up for better maintainability.
