Expand description

Client-facing error codes — transport-agnostic, mirrors proto ErrorCode.

Values are intentionally kept in sync with proto so that server-layer conversions (core::ErrorCode ↔ proto::ErrorCode) are trivial numeric casts. If a new variant is added here, add it to proto’s .proto file too.
