polyglot-parity

Drive a feature or fix through all 5 smooth-operator implementations (Rust · C# · Python · TypeScript · Go) and prove parity with the shared conformance corpus. Use when changing the protocol/engine/server in this repo and the change must land in every language — triggers: "propagate to all languages", "keep the polyglot in parity", "update all 5 servers/SDKs", "port this to C#/Go/Python/TS", "did I miss a language".
