feat: add dependency freshness checker — issue #161

Implements scripts/dependency_freshness.py which compares installed
dependencies against latest PyPI versions and flags packages that are
more than 2 major versions behind. Includes comprehensive tests in
scripts/test_dependency_freshness.py.

Closes #161
