# Task

Implement **`solution.py`** with `parse_int_list(text: str) -> list[int]`: parse a string
containing a JSON array of integers (e.g. `"[1, 2, 3]"`) into a Python list of ints.
Proposed solution
```python
import json

def parse_int_list(text: str) -> list[int]:
    """
    Parse a string containing a JSON array of integers into a Python list of ints.
    
    Args:
        text (str): A string representing a JSON array of integers, e.g., "[1, 2, 3]"
        
    Returns:
        list[int]: A Python list containing the integers from the JSON array
        
    Raises:
        json.JSONDecodeError: If the input string is not valid JSON
        TypeError: If the parsed JSON is not a list
        ValueError: If any element in the list is not an integer
    """
    try:
        parsed = json.loads(text)
        
        # Verify that the parsed result is a list
        if not isinstance(parsed, list):
            raise TypeError("Input must be a JSON array")
            
        # Verify all elements are integers and convert them to Python int
        result = []
        for item in parsed:
            if not isinstance(item, int) or isinstance(item, bool):
                raise ValueError(f"All elements must be integers, got {type(item).__name__}")
            result.append(item)
            
        return result
        
    except json.JSONDecodeError as e:
        raise e
