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 Signed-off-by: Abhinav Sinha <[email protected]>

Unlike a liveness probe (which restarts containers), a failed readiness probe removes the pod from Service endpoints until it recovers.\n\n**Your task:**\n\nCreate a Deployment named `ready-app` with:\n- Image: `nginx:alpine`, 2 replicas\n- A **readiness probe**: HTTP GET `/` on port `80`, `initialDelaySeconds: 3`, `periodSeconds: 5`",
