Mirror source directory structure in tests

Test paths now match source paths:
  schema/models.py     → schema/test_models.py
  schema/resolver.py   → schema/test_resolver.py
  schema/presets.py    → schema/test_presets.py
  schema/formats.py    → schema/test_formats.py
  experiment/config.py → experiment/test_config.py
  experiment/controller.py → experiment/test_controller.py

Root-level tests (test_load_recipe.py, test_pipeline.py, test_bridge.py)
stay at the recipes/ test root matching their source location.
