Implement automatic pipeline rebuilding when stages are toggled or parameters change, while preserving camera and display state.

This is a specific enhancement to the Pipeline Mutation API (issue #35):

Requirements:

  • Detect when stage configuration changes
  • Rebuild pipeline while preserving camera position and display state
  • Maintain UI panel state during rebuild
  • Ensure smooth transitions without visual glitches

Implemented in commits:

  • 0eb5f1d: Implement pipeline hot-rebuild with state preservation
  • 238bac1: Complete pipeline hot-rebuild implementation with acceptance tests

The pipeline now supports:

  • Auto-injection of MVP stages for missing capabilities
  • State preservation during hot-rebuild events
  • Rebuild execution order after mutations
  • Minimum capability validation and enforcement

New files added:

  • engine/effects/plugins/afterimage.py
  • engine/effects/plugins/motionblur.py
  • tests/test_camera_acceptance.py
  • tests/test_pipeline_rebuild.py
  • scripts/demo_hot_rebuild.py
