T8b949e/**

* Tracks per-request start times and reports round-trip durations for request/response handlers.

*

* Request handlers (traceroute, neighbor-info, …) call [start] when issuing a request keyed by its id, then

* [appendDuration] when the matching response arrives to annotate the user-facing text with how long the round trip

* took. Start times are stored in an atomic immutable map so [start] (any coroutine) and [appendDuration] (the handler

* scope) never race.
