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]>

Kubernetes provides `runAsNonRoot` and `runAsUser` to enforce this at the pod level.\n\n**Your task:**\n\nCreate a Pod named `nonroot-pod` in the `default` namespace using the `busybox:1.36` image (command: `sleep 3600`) with the following security configuration:\n\n- Pod-level `securityContext`:\n  - `runAsNonRoot: true`\n  - `runAsUser: 10001`\n  - `runAsGroup: 10001`\n- Container-level `securityContext`:\n  - `allowPrivilegeEscalation: false`\n  - `readOnlyRootFilesystem: true`\n- An `emptyDir` volume mounted at `/tmp` so the process has writable scratch space.\n\n```bash\n# Verify:\nkubectl get pod nonroot-pod -o jsonpath='{.spec.securityContext}'\n```",
