Radio links rarely read the same both ways — a route that carries cleanly
outbound can be marginal on the return — but Trace path only ever walked a
route in the direction it was built. Add a Reverse path action that flips the
walk's hop order (us → a → b → c becomes us → c → b → a), so one composed
route can be measured in both directions.
It lives only in path mode: a target-mode route is a symmetric boomerang, so
reversing it changes nothing. Reverse sits in the build-path group beside
Compose and adopts the flipped spec exactly like any other path change — the
forward run's aggregates clear (they described the other direction) and Trace
stays idle, so you flip, then trace; reverse again to go back. Both readings
persist to history for side-by-side comparison. Disabled, with the same
"compose a path first" note as Trace, until there's a multi-hop path to flip.
