This resolves issue #259 where requirements with environment markers like 'pysha3==1.0b1; python_version < "3.6"' would fail to parse. Changes: - Updated _parse_requirement() to evaluate markers and exclude non-matching deps - Updated _parse_content() with same marker evaluation logic - Added 5 comprehensive tests for marker support: - test_marker_true: Requirements with matching markers are included - test_marker_false: Requirements with non-matching markers are excluded - test_marker_with_other_requirements: Markers don't affect other packages - test_marker_complex: Complex marker expressions work correctly - test_marker_no_marker: Packages without markers are always included All 292 existing tests pass plus 5 new marker tests (297 total).
