Guard receive-path transport rendering 

Skip raw packet, decoded message, peer, and channel formatting when
transport logging is disabled. Keep message processing and wire
reads outside the guards so logging controls never affect IPC flow.

Also narrow the remaining pretty-struct TODO to require a
non-raising formatter with native-repr fallback.

(this patch was generated in some part by `opencode` using
`gpt-5.6-sol` (`openai`))
