Add 17 tests covering all aspects of the graph-based pipeline system:

- Graph creation and manipulation (7 tests)
  - Empty graph creation
  - Node addition with various formats
  - Connection handling with validation
  - Chain connection helper

- Graph validation (3 tests)
  - Disconnected node detection
  - Cycle detection using DFS
  - Clean graph validation

- Serialization/deserialization (2 tests)
  - to_dict() for basic graphs
  - from_dict() for loading from dictionaries

- Pipeline conversion (5 tests)
  - Minimal pipeline conversion
  - Effect nodes with intensity
  - Positioning nodes
  - Camera nodes
  - Simple graph execution

All tests pass successfully and verify the graph system works correctly
with the existing pipeline architecture.
