Fidelity wiki: extension points + native-ETC-vs-plugin diffs Auto-generated by generate-diffs.py (lives in this wiki repo, not in the plugin's main branch). Documents the plugin-extensions interfaces (NetworkProvider, ForkIdProvider, ProtocolScheduleCustomizer) plus per-class diffs against Besu's native ETC, removed in #9671 (commit 1167c5a544).
