Distributed KVStore (Python + FastAPI) — Quorum, WAL, and Live Demo

Live demo: (run ./run_cloudflare_demo.sh then paste the printed Share link here)

Try this in the UI

1. Probe /health → see leader & followers.
2. PUT (auto-leader) a key, then GET from followers.
3. Toggle Block repl on one follower → writes still succeed (W=2/3).
4. Toggle both followers Down → write fails with 503 (no quorum).
5. Restart a node → state recovers (WAL replay).
