fix(tests): correct dependency dummy metadata extraction

The test registry creation was looking for 'hatch_dependencies' and
'python_dependencies' keys, but the actual metadata structure uses
'dependencies.hatch' and 'dependencies.python' (nested structure).

This caused the test registry to be created without dependency information,
preventing dependency resolution from working correctly in tests.

Updated to use correct nested structure:
- metadata.get('dependencies', {}).get('hatch', [])
- metadata.get('dependencies', {}).get('python', [])
