chore(scripts): remove demo/proof scaffolding from the PR

Drop the three scripts that were scaffolding while building, not part of the
shipped feature:
- ci-driver-demo.ts        offline no-agent control-loop demo (covered by tests)
- ci-driver-live-agent.ts  manual LLM-drives-MCP proof (needs a key)
- record-demo.no-jest.ts   offline sample-recording generator (real --e2e records)

Keep the three the workbench actually orchestrates: e2e-full-run, render-snapshots,
replay-e2e. Update scripts/README.md + ARCHITECTURE.md accordingly.
