Add Type Hints to jam.py

[UnitaryIron]

Task

Add Python type hints to all functions in jam.py.

Goal

We want to improve code readability, provide better IDE support, and catch type-related bugs early through static analysis.

Suggested Approach

• Review each function in jam.py.
• Add type annotations for parameters and return types.
• Use standard types from typing like List, Dict, Union, etc.
• After adding, validate using a type checker like mypy.

Requirements

• Familiarity with Python type hints (PEP 484).
• Ability to interpret function logic to deduce types.
