Introduce decker.ts (opstack recipe, host-process op-rbuilder, flashblocks, chain-monitor) as the primary local devnet flow, with a `just devnet` target and a rewritten local-testing/README.md. The builder-playground path (playground.yaml, run-playground) is kept fully intact as a deprecated fallback during the transition.

Pull request overview
Adds a decker-based local devnet “inline recipe” for op-rbuilder, including a small Prometheus+Grafana observability overlay and updated documentation so developers can spin up the stack via just devnet.
Changes:
- Document decker-based local devnet usage and workflows (quickstart, ports/services, traffic generation).
- Add
decker.tsmanifest that composes the upstream opstack recipe with an observability overlay. - Add a
just devnethelper and ignore the.decker/runtime/clone directory.
