### `Surface` trait + zero-sized type tags `hive-agent`'s wire types (`AgentRequest` / `AgentResponse`, aliased as
`ManagerRequest` / `ManagerResponse`) and its turn loop are factored
`AgentRequest` / `AgentResponse` (= `ManagerRequest` / `ManagerResponse` — through a small `Surface` trait with one zero-sized impl, so the loop
type aliases) are the wire types. There is one role: agent. itself has no per-role branches. See `hive-agent/src/main.rs`'s module

`main()` calls `serve_main::<AgentSurface>` for all roles. The turn
loop (`serve_loop` / `handle_turn`) has no per-role branches.
