chore: Fix some style issues

[fsbraun]

Summary by Sourcery

Refactor tuple parsing to use a compiled regex and update type annotations to use PEP 604 union syntax.

Enhancements:

• Extract and compile the tuple-splitting regex into a module-level constant and switch to fullmatch.
• Update return and parameter annotations to use the | union operator (e.g., str|tuple[str,str], list[str|tuple[str,str]]).
• Align docstrings with the updated type annotations.

Reviewer's Guide

Centralize the tuple-parsing regex into a reusable constant and update type annotations and docstrings to use Python 3 union syntax.
