Objective

Implement delimiters_balanced, a function that validates nested delimiters in a string.

Steps

• Create delimiter_stack.py.
• Expose def delimiters_balanced(text: str) -> bool:.
• Treat (), [], and {} as delimiter pairs.
• Characters that are not delimiters must be ignored.
• Return True only when every closing delimiter matches the latest unmatched opener.
• Return True for a string that contains no delimiters.
