[REF] Modernize type annotations 8 months ago

AI Summary: This issue proposes modernizing the project's type annotations by leveraging Python 3.10+ features. The goal is to replace `typing` module imports (e.g., `typing.List`, `typing.Union`) with native type hints (e.g., `list`, ` | `) to simplify the codebase.

Complexity: 2/5
