Update syntax to Python >=3.9

[hagenw]

Updates syntax to Python >=3.9 by removing the use of typing.

Summary by Sourcery

Update type hints across core modules to use Python 3.9+ syntax, replacing typing module constructs with PEP 585 generics and the native union operator.

Enhancements:

• Adopt PEP 585 built-in generics by replacing typing.Dict, typing.List, typing.Tuple, and typing.Callable with dict, list, tuple, and Callable annotations
• Replace typing.Union and typing.Optional with the native | union operator and import Sequence from collections.abc
• Add future.annotations and remove redundant typing imports to streamline type hints for Python >=3.9

Reviewer's Guide

Refactor all type annotations to Python 3.9+ syntax by replacing typing.* generics and unions with built-in generics, PEP 585 collections, and PEP 604 union operators, and adjust imports for future annotations support.

Hey @hagenw - I've reviewed your changes - here's some feedback:

• Replacing typing.Any with object changes the type‐checker semantics—object is more restrictive than Any, so double-check that this change is intentional.
• Ensure all new annotation names (Callable, Sequence, etc.) are imported from the correct modules (e.g. collections.abc) since typing imports were removed.
• Confirm that using built-in generics like list[str] and dict[str, object] aligns with your minimum Python and tooling versions so no unexpected compatibility issues arise.
