- set useLatestBscClinet to true to compile geth with latest geth on
  github
- xargs -r to ignore error if no previous geth found

Add Dockerfile and environment setup for BSC cluster

- cause in local Pebble take too much of my storage space

- allow monitoring access from the host machine via Docker port forwarding.

Feat/storage optimized and metrics access

* fix: prevent OOM kills by geth cache limit

- Without this, geth implicitly bumps the default cache to 4096MB when treating the setup as mainnet, which instantly exhausts Docker's memory limit (~8GB) when spinning up a 4-node local cluster.

* Add comments to clarify code logic

* feat: new script for docker spin up

- modify p2p address from localhost to use docker internal DNS name
- only handle geth initialization, but not start the node

* feat: implement dynamic compose generation

- Introduce `NODE_TYPE` and `NODE_INDEX` environment variables to uniquely identify each container and correctly mount its respective data dir (`.local/nodeX`).

* feat: add docker entrypoint for bsc cluster

- Makefile for lifecycle
- docker initialization script "node_entrypoint.sh" for booting geth
  based on node type (validator, sentry, fullnode)

* fix: redirect geth logs to docker stdout

forces Geth to output logs to standard output instead of local files, enabling docker's default logging driver to capture

* feat: optimize geth build cache

- Replaced `mv` with `cp` when extracting the compiled geth binary.
  prevent redundant rebuilds.
- Removed unused `exit_previous` func
- Add cluster-restart for fast restart without wiping blockchain data or
  trigger re-initialization.

* docs: update readme with sequence diagram

…on flow (#5)

Improves the BSC load test environment, including validator registration automation and protocol alignment.
It ensures the BSC cluster can work smoothly with the load tester.
