Installation fails on Python 3.13: xmldict==0.4.1 is unused but breaks pip install

[jimisola]

Problem

Installing reqstool on Python 3.13 fails with an ImportError from xmldict's legacy setup.py, which is incompatible with modern setuptools.

Root Cause

xmldict==0.4.1 is declared as a dependency in pyproject.toml but:

1. Never imported or used anywhere in the codebase (src/ and tests/ have zero references)
2. Uses a legacy build format incompatible with Python 3.13
3. All XML parsing in the project uses the stdlib xml.etree.ElementTree (see testdata_model_generator.py:6)

Solution

Remove the unused xmldict==0.4.1 dependency from pyproject.toml line 62.

Verification

• Codebase contains zero references to xmldict (confirmed via grep)
• All XML parsing uses stdlib xml.etree.ElementTree
