Abhinav Sinha 124e5276d4 refactor(scenarios): split monolithic configuration into individual files
- Split `scenarios/scenarios.json` into individual JSON files under `scenarios/data/` named `<scenario-id>.json`
- Split `scenarios/bundles.json` into individual JSON files under `scenarios/bundles/` named `<bundle-id>.json`
- Updated `backend/server.js` to dynamically load scenario and bundle files from their respective directories
- Updated documentation in `scenarios/SCHEMA.md` and `README.md` to reflect the new repository layout and contributor workflow
