Seamless Character & Environment Consistency

[SohailAwg]

Summary

• Add a cell-by-cell RunPod/Jupyter notebook for first-shot smoke tests and full multi-shot runs.
• Add documentation and first-run README setup guidance, including secret handling and reference-image workflow.
• Auto-enable the bundled plugin once for existing configs and ignore local secrets/large binary model artifacts.
